If you’re hoping to learn more about Chip Kelly’s offense, there are plenty of valuable resources out there that can explain it better than I can. If you’ve already been exposed to Chip when he was at Oregon, earlier we linked to Smart Football’s piece on what coach brought to the NFL in his preseason debut versus the Patriots on Friday.
If like a lot of Eagles fans you’re new to Chip, here’s a great place to start: FishDuck’s tutorial to the inside zone read, a staple of the offense. They do a lot of this, minus the quarterback taking off (only Matt Barkley performed a keeper against New England), so if you haven’t been learning on your own already, now is a good time start brushing up.
Here’s an excerpt from the Smart Football look at how the Eagles used the inside zone read against the Pats.
Although Kelly's version of the inside zone is typically associated with the read-option element he often added to it at Oregon, against the Patriots, Philadelphia almost never asked its quarterback to read a defender and decide whether to hand off or run it on an inside zone. (Of the Eagles' top three quarterbacks, only Matt Barkley ended up with a keeper on the inside zone read.) Instead Kelly relied on other complementary tactics to make the play go. The first was his other bread-and-butter inside run, power, which asks the linemen on the play side to block down and double-team the defensive linemen, while a backside guard pulls around and leads up on the linebacker.
Kelly has long added a misdirection element to his version of power by offsetting the running back to the side the play is headed. By doing this, Kelly's power, with its down blocks and the runner crossing in front of the quarterback, looks to the defense exactly like his inside zone, only going the other way. That is until the pulling guard appears, and then it's too late. Oregon dropped 47 points on a USC defense orchestrated by current Seattle head coach Pete Carroll with this simple adjustment.
There was one aspect of the offense I wanted to highlight myself though, and that is how nice it was to have most of the offensive line intact. Jason Peters didn’t suit up for the first game, but it didn’t seem to matter. Save for one breakdown when Nick Foles was in the game, the unit protected both quarterbacks well. Just look at the pocket Vick had to step into on his 47-yard touchdown pass to DeSean Jackson.
When’s the last time No. 7 looked that comfortable? He’s standing perfectly upright, not looking to escape. He has space to step into his throw without worry or care, and as a result is able to deliver a perfect strike for six points. With a healthy line, and an experimental scheme, it would appear the Birds’ offense is in store for a big season – I’m starting to believe regardless of who is under center.
Hey, Nick Foles played well (minus a fumble that wasn’t all his fault), but Vick hit the big play. Few quarterbacks throw the deep ball as well as the four-time Pro Bowler. Had ice water running through his veins on third-down conversion before that, and made the right read. Underthrew one pass, but 4/5 for 96 yards and a score in two series is tough to beat.
Same old Jason Avant. Had three catches, all for first down, two of them on third down. Good for 42 yards total. Reliable as always, and seems to have no trouble finding open space in Chip’s scheme.
Haven’t talked about him much, but DeSean is having a great camp. That carried over into the preseason with a 47-yard bomb against Aqib Talib. Jackson has been doing that sort of thing pretty much every day in practice, and he seems primed for a big year.
Not sure his stock is falling as much as he had one bad night. Missed a block pulling out in front of Chris Polk that resulted in the run to get stuffed. Worse, missed a block that allowed a rusher to get a free shot at Nick Foles, resulting in a fumble. Nothing but quality otherwise, but that turnover was huge.
Strong debut for the fourth-overall pick in the draft. Looked like he belongs. Wasn’t confused out there. Put a hat on somebody on every play, and didn’t get beat. Is still a little more natural run blocking, even getting out to the second level on a few occasions, but held his own in pass protection. Impressive start for the big man.
With all the emphasis we’ve placed on tight ends during the offseason, who would’ve thought Clay Harbor would be the one to wind up in here? Had more yards (47) on his three catches than all other tight ends on the team combined (41 on eight receptions). All three catches went for first downs, including a conversion on 3rd and 20. Apparently he’s Matt Barkley’s security blanket.
Never mind that he’s been stuffed at the bottom of the depth chart. Dropped two passes on Friday that were right in his hands, just a lack of concentration. Ran hard, but not extremely well, carrying eight times for 31 yards. Played behind second- and third-string offensive line, so hard to judge, but hasn’t stood out this summer.
Brown had a strong night running the football, rushing five times for 22 yards and a touchdown – much better than Chris Polk, who was ineffective on four carries for seven yards. But where Polk still had an edge was pass protection. Polk had a key block on Vick’s touchdown pass, whereas there were a couple times it appeared Brown should’ve thrown a block, but was out of position or left the backfield early. Amazing pure talent, still rough around the edges.
First of all, Celek was the starting tight end. The Eagles didn’t use a ton of two tight end sets early on, and he got the nod with the starters. He also proved to be more valuable than many of us realized, as it turns out he’s the emergency long snapper – albeit not a very good one. Had only two catches for 10 yards though, and big minus, he fumbled once. Not a great outing, but shouldn’t diminish his role.
Great, Barkley eventually led a scoring drive on his sixth series. Got more comfortable as the game went on. Earlier he threw into coverage a bunch. Some of his balls seemed to lack zip, wobbled. Finished 11 for 22, 103, TD. Granted Barkley was playing with backups, but Foles looked better in the preseason last year. Not close to winning the starting quarterback job, that’s for sure.
