All-22: Nick Foles Brilliant Against the Washington Redskins

The Philadelphia Eagles squared off against the Washington Redskins this past Sunday in what turned out to be another in a long line of classic NFC East divisional games. For the third straight week, Nick Foles lead a 4th quarter game winning drive in what my opinion was the best game he’s played in his career. Yes, even better than his seven touchdown performance against the Oakland Raiders last season. Foles put the team on his back Sunday and carried them across the finish line, and he took a heck of a beating while doing it. He completed just about every throw in the book on Sunday; square outs, curl routes, seam routes, fly routes, crossing routes, etc… and he did so while under extreme duress at times. So in this week’s All-22, I’ll take a look at some of the key passing plays from this past Sunday.

On this first play, Foles completes a touchdown pass to rookie wide receiver Jordan Matthews for Matthews’ first career touchdown. I highlighted this play to show the importance of the rushing attack for this offense and how geared up Washington was to stop it. Look at how linebacker Perry Riley bites hard on the playaction fake, leaving a wide open space behind him for an easy pitch and catch between Foles and Matthews.

This next play comes on 2nd and 5 on the Eagles final drive of the first half. Foles rolls out to his left and is able to hit Matthews in stride for a first down. Foles makes this play look easy, but it is no simple task to hit a guy in stride while rolling out to your left. Not to mention that had this throw been just slightly behind Matthews it would have been broken up by safety Brandon Meriweather.

Four plays later, Foles hits Matthews for another touchdown on the same route they scored the first one on. This time there is no playaction before the throw. Perry Riley has tight coverage on Matthews, but it doesn’t matter as Foles fits this ball in there perfectly and Matthews does a great job of hauling in the pass while getting both feet down in the end zone. Look at how Foles throws with anticipation on this play. At the time he begins his windup, Matthews isn’t even at the same depth as Riley, let alone behind him.

Here is a look from behind the line so you can see what Foles was looking at on this play and how tight a window he was throwing into. The other key part about the timing of this throw is that by the time Riley turns his head to look back for the pass, it’s too late and he is unable to get his hands to the ball as it’s going over his head.

This next play comes from midway through the fourth quarter on the Eagles’ go-ahead drive. It’s 3rd and eight, and Foles delivers a strike to Jeremy Maclin on a deep curl route in the face of pressure. Maclin does an excellent job of catching this pass and getting his knee down. This play was initially ruled as an incomplete pass but was overturned on a challenge by Chip Kelly. Once again, look at the anticipation by Foles. He begins his windup before Maclin even makes his cut. Had he waited until Maclin made his cut to throw, the cornerback would have had a chance to make a play on this ball.

Here is a look from the end zone view so you can see the pressure Foles was under on this pass. The Skins run a double stunt to perfection on this play, freeing up Brian Orakpo and Ryan Kerrigan to get a clean shot on Foles. It is no matter though, as Foles stands tall, plants his feet, and delivers this throw knowing full well he is about to take a big hit.

Two plays later, Foles hits Maclin on a seam route for the go-ahead touchdown. Maclin shows on this play that he knows the tricks of the trade when it comes to route running. Watch as he starts off on this play running on a slight angle to his right. This gets Meriweather’s hips pointed to the outside. Maclin then cuts back to the inside, forcing Meriweather to change his hip position as he turns to run downfield, during which time Maclin is able to get separation and beat Meriweather down the field. It’s those little nuances of route running that can make the difference between getting open and being covered.

This final play was Foles’ last throw of the game. The situation is 2nd and 11 with 1:43 left to play. A first down wins the game as the Skins only have one timeout left. Foles is going to roll out to his left and hit tight end James Casey on an out route for the game clinching first down. Great playcall by Kelly, and great execution by Foles and offense. Foles fits this ball in there perfectly, throwing it into Casey’s gut as opposed to leading him out in front, preventing cornerback David Amerson from getting his hands to the ball. It should be noted that he was also able to do this while he had Meriweather coming full speed ahead at him.

Here is a look from behind, so you can see the ball placement and how it prevented Amerson from being able to get his hands to the ball.

If he hasn’t done so already, Foles is starting to really turn some heads and prove that he isn’t just a quarterback who can put up big numbers when things are going good, but a quarterback who can win games in the face of adversity. Even Chris Collinsworth seems to be coming around on him based on my “brief discussion” with him via Twitter last night.

Well that raps up this week’s All-22 review. The Eagles head out west to San Fransisco this Sunday as they look to improve to 4-0 in what should be a hard fought game.


Can Jeremy Maclin replace DeSean Jackson? The Answer is Yes

DeSean Jackson may have had some issues with teammates and coaches in the locker room, but there is no doubt that he was a very productive player on the field for the Philadelphia Eagles in 2013. But I have to think that the Eagles made the move of releasing Jackson with the belief that Jeremy Maclin will be able to step in and fill the void. And when we take a closer look at the numbers, maybe that’s not such a far fetched idea after all.

Jackson had a career year this year, with career highs in catches, yards, catch % (percentage of targeted passes that were caught), and equalled his career high in touchdowns. But how much of that is due to Chip Kelly’s system and having Nick Foles throw him the ball? Obviously, Jackson has a lot of talent and is a very good player. So I’m not saying that he’s just some also-ran receiver that can be replaced by anybody. But what I am saying is that you can’t look at his numbers from this year and compare it to what Maclin has done the past 3 years, because we didn’t get a chance to see what Maclin can do in this system, and there’s a good possibility that Maclin sees the same type of explosion in production that Jackson saw.

So let’s get into the numbers so I can show you what I’m talking about.

Leading up to the 2013 season, here were DeSean Jackson’s numbers:
71 games, 274 catches, 524 targets, 4785 yards, and 23 touchdowns.
On a per game basis, this comes out to: 3.9 catches, 7.4 targets, 67.4 yards, 0.3 touchdowns.
Extrapolated to a 16 game season, this comes out to: 62 catches, 118 targets, 1078 yards, and 5 touchdowns.
Note that leading into the 2013 season, DeSean had only caught 52.3% of the passes thrown his way, and that his career high in a single season came in 2011 when he caught 55.8% of the passes thrown his way.
Now, here are Maclin’s career numbers:
59 games, 258 catches, 426 targets, 3453 yards, 26 touchdowns.
On a per game basis this comes out to: 4.4 catches, 7.2 targets, 58.5 yards, .44 touchdowns.
Extrapolated to 16 games that comes out to: 70 catches, 115 targets, 936 yards, and 7 touchdowns. Note that Maclin’s catch % for his career is 60.5%. So leading into the 2013 season, Maclin actually averaged more catches and touchdowns per year while catching a higher % of passes thrown his way, while Jackson averaged more yards.

Now here were Jackson’s numbers for 2013: 82 catches, 126 targets, 1332 yards, and 9 touchdowns. Compared with his career averages, that’s a 32% increase in catches, a 24% increase in yards, and an 80% increase in touchdowns. And in 2013 he caught 65% of the passes thrown his way, that’s nearly 13 percentage points above his career average entering this season, and 10 percentage points above his previous highest single season mark.

Earlier in this post I mentioned Nick Foles. The reason I did that is because without Nick Foles, DeSean Jackson was on pace to have another year where he caught less than 60% of his targeted passes. Here is the breakdown of complete stats for DeSean Jackson from each quarterback this past year:
Michael Vick: 25 catches out of 44 targets (57%), 463 yards (18.5 yards per catch and 10.5 yards per target), and 2 touchdowns (1 touchdown per 12.5 catches 22 targets).
Matt Barkley: 7 catches out of 12 targets (58%), 61 yards (8.7 yards per catch and 5.1 yards per target), 0 touchdowns.
Nick Foles: 50 catches out of 70 targets (71.4%), 808 yards (16.2 yards per catch and 11.5 yards per target), and 7 touchdowns (1 touchdown per 7.1 catches and 10 targets).

So it’s clear that with Nick Foles throwing him the ball, Jackson became a much more efficient receiver, hauling in 71% of the passes thrown his way, which was the highest mark of ANY wide receiver in the NFL this past year.

If Jeremy Maclin sees just HALF the increase in production that DeSean Jackson saw last year, his numbers for 2014 will look like this: 81 catches, 1048 yards, and 10 touchdowns. If he ends up seeing the same increase in production, his numbers will look like this: 92 catches, 1160 yards, 13 touchdowns.

So is it really that far outside of the realm of possibility that Maclin puts up numbers somewhere in the range of the 2 sets of values I just posted? Considering what playing in this system did for DeSean Jackson, I don’t think so.

“But Larry, Jeremy Maclin put up those numbers in Reid’s system while playing next to DeSean Jackson, he won’t have that luxury this year” That’s something I’ve heard from many people when I tell them that I think Maclin will have a career year just like Jackson had last year, and it is certainly a valid point. Now, it’s a small sample size but remember that at the end of 2012, DeSean Jackson was out with an injury for the final 5 games of the season. So we saw then the same scenario we are going to see this year, with Foles as the quarterback and Jeremy Maclin and Riley Cooper as his starting receivers.
Here were Maclin’s numbers over those 5 games;
28 catches, 353 yards, and 3 touchdowns. Over a 16 game season that would come out to 90 catches, 1130 yards, and 10 touchdowns. Now like I said, it’s a small sample size so I’m not saying that he would have produced those exact numbers in 2012 had he been the primary receiver and Jackson not have played. I’m just using that extrapolation to show that those numbers over a period of 5 games is solid production.

So there you have it. That is my case for saying that Jeremy Maclin will step up this year and have a career year in this system and will replace the void left by the departure of DeSean Jackson.

Philadelphia Eagles vs Detroit Lines All-22 Film Review

What a game, what a game, WHAT A GAME!  I’ll keep this short and sweet and let you know up front that there won’t be much “analysis” going into this week’s All-22 review. I can’t even use any film from the first half since the snow was so bad it was hard to even make out who was who while watching it. So what I have done here is take 5 big runs from the monstrous 4th quarter the Eagles put up and will show them here from the endzone view so you can see how the line opened up the holes they did.

In the first half, I felt that Chip Kelly was calling too many east/west runs for the weather conditions. I think what we saw in the 4th quarter was a combination of the following things: Kelly calling more north/south runs, McCoy hitting the hole harder, and the offensive line getting a great push and wearing down the Detroit Lions’ defensive line. In a game in these types of conditions, it’s all about momentum. Once you can get a solid push on the guy you are blocking, it’s very hard for that player to recover and stop you from pushing him backwards. I also think that in this game, you saw the difference in conditioning between the Eagles and the Lions. When the ground is covered in snow like that, it makes it that much harder to move and you have to exert extra strength and take extra strides to move the same distance you normally would. And I think that played a big factor into why by the 4th quarter, the Eagles’ offensive and defensive lines were able to win the battle in the trenches.

First up is McCoy’s 40 yard touchdown run. Todd Herramins does a great job of clearing Ndamukong Suh out of the hole, and Lane Johnson does a great job of getting to the second level and putting a block on linebacker Stephen Tulloch, and Shady does the rest on this 40 yard TD scamper.

Next up is McCoy’s 57 yard TD run a few minutes later. The line again does a great job of opening up a running lane for McCoy, and this time Jason Avant makes a great block downfield to spring Shady for this 57 yard TD.

This next play is just ridiculous. Check out some of the jump cuts McCoy makes on this run. It’s like someone forgot to tell him that it had just snowed 6″. I literally have no idea how he was able to keep his footing on this run.

Nick Foles decides to get into the action on this next one, as he takes this read option keeper for a 20 yard gain.

Next up is Chris Polk’s 38 yard TD run to put the game out of reach and take a 34-20 lead. Tight end James Casey does a great job of getting across the line and putting a block on Lions’ safety Louis Delmas to seal off the weakside for Polk.

And finally we end with the 4th and 12 yard play to ice the game (no pun intended). This play is a simple read.  Foles has two options on this play, handoff to Chris Polk, or throw the seam route to Brent Celek. On this play, Foles reads the safety, and if the safety stays back, he hands off to Polk, if the safety bites on the run fake, then throw it to Celek. As you’ll see below, the safety comes in, making this an easy choice for Foles to make an easy touch pass to Celek to end the game.

Good teams find ways to win no matter the circumstance or conditions, and that’s what the Eagles did on Sunday. And with Dallas losing to Chicago on Monday night, the Eagles are now in sole possession of first place in the NFC East as they travel out to Minnesota for next week’s game against the Vikings.

Anatomy of a Play: Week 11 vs. the Washington Redskins

As this blog is brand new, this will be the first of what I plan on making a weekly segment titled “Anatomy of a Play”. In these segments, I’ll analyze a few key plays from the Eagles game using the All-22 coach’s film and show how and why the play developed the way it did, and try to show you things that may not have been made aware during the live broadcast of the game. In this week’s edition of Anatomy of a Play, I’ll analyze three offensive plays from the week 11 matchup against the Washington Redskins.  Here we go…

49 yard pass to LeSean McCoy on a Wheel Route

On this play, a simple wheel route turns into a 49 yard play due to the Eagles offense exploiting a mismatch in the Redskins defense. Here is a diagram of the play. McCoy wheel route_1st and 10

The route in red is McCoy’s. I have the other players’ routes in green and the Redskins assignments in yellow.  As you can see below, the Redskins are in man coverage, with one deep safety, but he is on the other side of the field from where McCoy runs his route. Furthermore, the Redskins have outside linebacker Ryan Kerrigan matched up 1 on 1 with McCoy, that’s a huge mismatch for the Eagles to exploit. And as you can tell, there is going to be nothing but wide open space for McCoy to run his route.  Foles hits him perfectly in stride which allows him to run for an additional 32 yards after he catches this pass.

Here is the play in motion

43 yard screen pass to Brent Celek

This big play is the result of a great play design and perfect execution.

celek screen_1st and 10

The player circled in red is Brent Celek. The three offensive linemen with red lines are (from right to left) Jason Peters, Evan Mathis, and Jason Kelce.  These are the three linemen who are going to go out to block for the screen.  The play starts by having Bryce Brown go in motion (shown in blue) which draws London Fletcher with him, clearing out the middle of the field.  Peters, Mathis, and Kelce do an excellent job of selling their blocks and waiting until the last moment to go out and block for the screen, which prevents the Redskins’ defensive linemen from sniffing this play out.

Here is the play in motion.  Watch in the middle as I pause the clip and circle Todd Herramins who lays an excellent crack-back block on a defensive linemen who might have had a chance of tackling Celek from behind.

19 yard pass to Desean Jackson on a Corner Route

This last play was not a huge play like the other two, but I wanted to highlight it because it really was a perfect pass by Nick Foles in difficult coverage, and it was on 3rd down with 11 yards to go.  Here is the diagram of the play.Djax deep out_3rd and 11

Jackson’s route is in red, with the other receiver’s routes in blue.  Washington is playing a zone defense on this play.  As you’ll see from the following clip, to complete this pass, Nick Foles has to throw this ball over the hands of the outside cornerback but put enough zip on it and throw it with such precise timing that it gets to Jackson before the safety can get there. If this ball had been late or underthrown, it is at risk at being intercepted. But Foles throws it with perfect timing and accuracy and completes it to Jackson for a 19 yard gain.  Here is the play in motion

Well that’s it for this week’s edition of Anatomy of a Play.  Hope you enjoyed it and have a great bye week!

Inside the Numbers: YAC YAC YAC

Yards after the catch, otherwise known as YAC.  It’s an important stat in any offense and it’s a staple of the Chip Kelly offense. It’s one of the main reasons why the Eagles lead the NFL in the amount of 20+ yard pass plays with 56.  The next closest team is the Denver Broncos who have 46 passing plays of 20 yards or more (The Eagles also lead the NFL with 16 passing plays of 40 yards or more). Getting good YAC is a sign of 3 things: a) A quality play design which results in a player having the opportunity to catch the ball in space, b) An accurately thrown pass that hits the intended target in stride and allows the player to run after the catch, and c) The intended target being able to haul in the catch while maintaining his speed and being able to make a play once the ball is in his hands. The Eagles got a ton of all three on Sunday vs. the Redskins and it was a big factor in their explosive offensive output.

Nick Foles completed 17 of 26 passes on Sunday for 298 yards.  Of those 298 yards, 178 of them came as a result of yards gained after the catch.  That’s nearly 60% of his total output. Furthermore, 178 yards on 17 completions comes out to 10.5 YAC per completion.  That’s a lot of YAC.

Some of these plays came as a result of properly timed and executed screen passes which caught the defense off guard, such as the 24 yard screen to Bryce Brown and the 43 yard screen to Brent Celek. Other plays came as a result of accurate throws by Foles which allowed his receivers to pick up chunks of yards after the catch, such as the 26 yard pass to Desean Jackson (24 yards gained after the catch), the 16 yard catch by Zach Ertz (12 yards gained after the catch). and the 49 yard pass play to LeSean McCoy shown below (32 yards gained after the catch).

Bonus Stat

Nick Foles has been performing very well against the blitz this year, consistently finding the open man and making teams pay for sending additional rushers.  Sunday was no exception.  The Redskins blitzed Foles 10 times.  Of those 10 blitz attempts, Foles completed 5 of 8 passes for 104 yards (13 yards per attempt), ran once for 7 yards, and was sacked once.  He would have completed 6 passes but Zach Ertz dropped a pass that would have gone for a first down.  4 of his 5 completions went for first downs, and on the play where he ran for 7 yards, he picked up a first down.  So out of the Redskins’ 10 blitz attempts, the Eagles picked up a first down on half of them.

As a defense, when you blitz it’s a battle of risk vs reward, and you hope that the reward of forcing the offense into a negative play (ie sack, incomplete pass, interception) outweighs the risk (giving up a big play, first down, touch down).  On Sunday, the Eagles won that battle.

Extra Point

Bonus points to me for resisting the urge to name this segment “YACkety YAC, don’t talk back”.

Key Matchups for Week 11 vs. Washington Redskins

It’s been 10 weeks since the Philadelphia Eagles took the Washington Redskins by surprise with their new offensive scheme, putting up 33 points of offense in just over 31 minutes of game time.  This Sunday is a date that I’m sure every Redskins player and coach has had circled on their calendars since then.  Some things have changed for both teams since the season opener.  For the Redskins, their offense is starting to come back to life as Robert Griffin III continues to shake off the rust stemming from his off-season recovery from knee surgery, and Alfred Morris is finding his stride as he’s averaged 112 yards and 5.1 yards per carry over the past 4 games.

For the Eagles, Nick Foles is now the quarterback and is on an incredible hot streak, Riley Cooper has emerged as a serious playmaker, and the defense is starting to find its groove as they’ve held their last 6 opponents to 21 points or less. Neither team can afford to head into this game thinking they are going to see the same team they saw in Week 1.

Here’s a look at two key matchups heading into the rematch between the Philadelphia Eagles and the Washington Redskins.

LeSean McCoy vs. Redskins’ Linebackers and Defensive Backs

This first one is not a 1 on 1 matchup, because frankly, you can’t tackle Shady McCoy with simply 1 defensive player.  The Redskins tried that in Week 1 and the results were dreadful for them as missed tackles lead to huge gains for Shady.  McCoy had 31 carries for 184 yards (5.9 ypc) in that week 1 game.  On 8 of those 31 carries, McCoy was able make a defender miss and pick up additional yards.  84 additional yards to be exact.  That’s over 10 yards per missed tackle, and is a sign of a team not swarming to the ball.  4 of those missed tackles lead to first downs, while 1 of them lead to a 34 yard touchdown (27 yards gained after the missed tackle). Now, I know it’s been 10 weeks, so here’s a few clips of McCoy making defenders look silly to refresh your memory and get your palette wet for Sunday’s game.

Ok, are you back with me?  Good. A big part of the reason the Redskins had so much trouble with the Eagles run game in week 1 is that for a majority of the game, their defense played with 2 deep safeties.  This is an absolute no-no when facing a Chip Kelly offense.  Since Kelly likes to run a lot out of spread formations (mostly shotgun with 1 tight end and 3 wide receivers), playing with 2 deep safeties opens up too many opportunities in the run game as the defense becomes too spread out to be able to swarm to the ball effectively.  It also opens up easy opportunities for the Eagles to run their basic read option play, where the 3 options are 1) handoff to the RB, 2) seam route to the TE in the middle of the field, and 3) bubble screen to the slot receiver.

When a defense plays with 2 deep safeties against this read option play, it forces their 2 linebackers to have to guard against the run AND a pass to the tight end at the same time.  If a linebacker goes to cover the tight end, it leaves 5 guys in the box which opens up huge lanes for the runningback.  If both linebackers stay in the box, then the tight end will be open on the seam route for an easy pass, such as what happened on this play from week 1 which resulted in a 28 yard pass to Brent Celek.

And here’s what happened when one of the linebackers went to cover the tight end, leaving only one linebacker in the box to guard against the run. photo 03_zps0d5d6897.jpg

You could drive a truck through this hole. photo 04_zpsb49e9b66.jpg

So look for the Redskins to bring one safety closer to the line of scrimmage this week and play him over the tight end, which will allow the two inside linebackers to keep their attention focused on LeSean McCoy and the run game. And if the Redskins want to stand a chance against the Eagles tomorrow, then they’re going to have to do a much better job of swarming to the ball and paying much more attention to McCoy than they did in the week 1 matchup. This should open up some big opportunities in the passing game, which brings me to my second key matchup of the day…

Riley Cooper vs. Josh Wilson/David Amerson

Despite Riley Cooper’s recent emergence, Desean Jackson will still be the Redskins’ primary concern in the passing game.  And with only one safety playing deep, Jackson will undoubtedly draw double coverage more often than not.  This will leave Riley Cooper single covered for a good portion of the day like he has been in recent weeks.  Cooper has been a key cog in the Eagles offensive explosion these past few weeks (in addition to the obvious key player in Nick Foles who has thrown 16 touchdowns and 0 interceptions so far) as defenses have been daring the Eagles to beat them by throwing to Cooper. And the Eagles and Cooper have been doing just that. In the past 5 weeks, Cooper has caught 20 passes for 462 yards (23.1 yards/catch) and 6 touchdowns and has shown that he can make teams pay when he’s left single covered.

The 6’3″ Cooper has a 6″ height advantage over the 5’9″ Josh Wilson.  If Wilson is matched up against Cooper in single coverage, look for the Eagles to try to take advantage of this early and force the Redskins to make an adjustment to their defense. Because of this height difference, the Redskins may look to put 6’1″ rookie cornerback David Amerson on Riley Cooper.  While he is most likely a better matchup from a physical standpoint, he’s also a rookie.  And we all saw what Riley Cooper did to rookie D.J. Hayden (who was the 12th overall pick of this years draft) two weeks ago in Oakland.

It will be interesting to see what adjustments the Redskins make to try to slow down the Eagles offense, and it will be even more interesting to see what Chip Kelly comes up with to exploit their adjustments.

Chip Kelly: He’s Playing Chess While His Opponents are Playing Checkers

One thing that Chip Kelly has done an excellent job of in the passing game, is anticipating how the defense is going to play us on a certain situation, and dialing up a play to exploit their set up.  At times, this causes their defense to be in a situation where they have a lone defender having to cover two people at once.

An example of that from the Green Bay game was the deep post route that Nick Foles connect with Riley Cooper on for a touchdown.  Here is a diagram of that play:cooper diagram

We run a playaction on this play that sucks the 2 linebackers in.  Brent Celek blocks on the right side of the line to sell the fake.  After the fake, Bryce Brown continues to run to the flat, where the safety has to pick him up.  Zach Ertz runs across the field behind the line of scrimmage which draws the nickle back in to make sure he isn’t going out for a pass.

We only had 2 downfield routes on this play.  DeSean Jackson runs an intermediate crossing route, and Cooper runs a deep post.  Jackson beats his man to the inside and is open running across the field, and since the playaction caused the linebackers to take their first steps towards the line, there is plenty of room to drop a pass in over their heads to Jackson.  Meanwhile, Cooper has inside position on his man as he runs downfield.

The deep safety now has a conundrum.  If he drops back in coverage to provide over the top help for Cooper, he’ll leave Jackson wide open across the middle, and if he comes up to help cover Jackson, then the cornerback has no inside deep help for Cooper. The safety ends up taking his first few steps towards Jackson, which is all the movement Foles needs to be able to put the ball in space for Cooper to run under.  As the safety tries to turn around and head back towards the endzone, it’s too late and he’s unable to get to the ball.

Now, the throw wasn’t perfect.  A perfect throw would have gone a few yards into the endzone so that Cooper wouldn’t have to take such a hard angle at the last second and make a diving catch, but it was thrown in the perfect spot horizontally, which doesn’t allow the CB to catch up to it, and doesn’t allow the safety to recover and make a play on the ball.

Here is a picture from the All-22 film just as Foles is about to throw the ball downfield.  As you’ll see, had the safety dropped back to provide over the top help for Cooper, Jackson would have been wide open for an easy throw that could have turned into a big gain.

This next play is the corner route touchdown pass to Riley Cooper.  We again run playaction which draws the linebackers in.  Brent Celek runs across the field behind the line to then block the edge rusher on the right side of the field.

The outside corners are in man coverage. Jeff Maehl is going to run a deep post route, taking his man with him.  Desean Jackson is going to run a circle route, taking his man with him while also occupying the safety on that side of the field.

The nickle corner over Cooper is playing a short zone, he’s going to release Cooper to the safety behind him, and then he’s going to start running towards LeSean McCoy in the flat.  This is where the fun begins.

The safety is now 1 on 1 with Cooper and he has absolutely no inside help.  Cooper is going to run a fake slant route, and then cut to the outside and run a corner route.  He does an excellent job of selling the slant route, causing the safety to bite and take a few steps forward, and when Cooper makes his cut, the safety is completely off balance and out of position to recover, leaving Cooper wide open for an easy pitch and catch.

Here is the diagram of the play:

And here is the All-22 picture, showing the point at which Cooper is running his fake slant route and about to turn it into a corner route. With Jeff Maehl taking his man with him on the deep post route, there will be nothing but open space for Foles to throw too for Cooper’s corner route as the safety bites on the fake slant.

Plays like these are why the Eagles currently lead the entire NFL in plays of 20 yards, 30 yards, and 40 yards.
