When the Eagles drafted Fletcher Cox in 2012, then-defensive line coach Jim Washburn was ecstatic.

“When God made him, he made him to be in this system right here,” Washburn said at the time.

He was of course talking about the Wide-9. Cox’s job last year was to pin his ears back and get into the backfield on every snap. On a defense that was a disaster, Cox was one of the few bright spots, finishing the year with 5.5 sacks, 24 hurries and seven tackles-for-loss.

But with the offseason changes came a new defensive scheme that now calls for Eagles defensive linemen to two-gap (All-22 explanation here) and play with discipline, rather than just attack.

“I think I’ve been doing a good job at it,” Cox said. “A lot of room for improvement. Just a lot of little things that I’m not doing right. At the end, once I get rolling, I think it’ll all come together.”

Some are already linking Johnny Manziel to Chip Kelly. “Oh my gosh. He would be the prototype,” said one NFC GM.

In Week 1, Nate Allen was on the field for 67 plays while  Earl Wolff saw only eight snaps. This past Sunday, Wolff’s number jumped up to 49 snaps and Allen’s dipped to 63.

If those numbers are any indication, the rookie is gaining on the struggling veteran.

“I really appreciate [the way the coaches are working me in,] said Wolff, who was also part of a three-safety look Sunday due to depth issues at corner. “Every rep is an opportunity. Regardless of how many reps I get, if it’s 10, if it’s 20, if it’s five, I just want to go out there and take advantage of every single opportunity I get.”

The question is when Wolff will be prepared to take over the spot on a full-time basis.

Chip Kelly has 25 seconds to talk through the headset to Michael Vick in between snaps.

From the time the play clock starts until there are 15 seconds remaining, the one-way line of communication is open. So the question posed to Kelly today was: What do you say to Vick other than the play-call?

Here’s what we saw from the ‘D’ after having re-watched Sunday’s contest.

DeSean Jackson caught a career-high nine passes on Sunday against the Chargers. He finished with 193 yards, second only to his memorable 210-yard outburst against the Cowboys in December of 2010. It was a monster day. And it could have been much bigger.

His 37-yard touchdown was negated by an illegal formation penalty in the third quarter. And he and Michael Vick just missed hooking up on a few long bombs before finally connecting on a 61-yarder late in the third.

“That’s very frustrating, honestly. The touchdown got called back, there was one I caught out of bounds when my right foot stepped out, then the overthrown one that slipped off of my hands,” Jackson said. “But that’s part of the game. We just have to keep going and keep working. Overall, I felt I had a great game.”

A big reason Jackson was still able to excel is because he was active in the short game as well. In seasons past, it was often feast or famine, where productivity was largely tied to whether he hit on the big play. Not so much this year.

Here’s a position-by-position review of the Eagles’ offense after having reviewed the game

Mychal Kendricks looked a little hobbled as he walked around the locker room following Sunday’s loss to the Chargers.

“It’s football,” said Kendricks. “Everyone’s dinged up.”

The second-year linebacker has a groin injury, turns out, though he was listed as a full participant for Monday’s practice.

Brandon Boykin (quad), Brent Celek (shoulder) and  Jason Kelce (thumb) were the other new names on the injury report. Celek was hurt on the same play that Michael Vick was banged up on late in the contest. Both players only missed one down before re-entering the game. Vick was not listed on the report.

Chip Kelly conceded during his day-after press conference that, in hindsight,  he would have handled a couple things differently down the stretch Sunday against the Chargers.

“I’ve made mistakes, I think we’ve all made mistakes,” he said. “No one coaches a perfect game, no one plays a perfect game, but you have to learn from those mistakes and hope they don’t happen again.”

Chip Kelly recognizes that the Eagles have a safety issue. The problem? It looks like there might not be a solution.

“Right now?” Kelly asked after Sunday’s loss to the Chargers. “There aren’t any safeties on the street, I can tell you that. So we’re going to play with the ones we’ve got.”

Raise your hand if you take that as a ringing endorsement of the players on the roster.

Here’s a look at Eagles snap counts against the Chargers, with notes on Brandon Graham, James Casey, Earl Wolff and others.

Lane Johnson was assigned to Dwight Freeney for much of Sunday’s game, so you can understand why the rookie was  trying to gain any advantage he could think of.

One trick of the tackle trade is to line up as far back as possible while still remaining on the line of scrimmage.

“I think you’ll see that a bunch with tackles in the NFL because you have such fast guys and any advantage you can get, you’re going to try and get…It’s a fine line,” said Johnson.

He crossed that line more than once against the Chargers, at least according to the referees.

The Eagles’ offense piled up 511 yards Sunday afternoon, scoring 30 points and averaging 8.8 yards per play.

Michael Vick completed 23 of 36 passes for 428 yards and two touchdowns, averaging 11.9 yards per attempt. LeSean McCoy totaled 167 rushing/receiving yards. And DeSean Jackson had nine catches for 193 yards.

In the second half, the Eagles scored on every possession except for the final one when they got the ball with seven seconds left.

Yet, given the nature of Sunday’s three-point loss, it was clear afterwards that Chip Kelly and the offensive players felt they should have done more.

Philip Rivers completed 77 percent of his throws Sunday. Threw for 419 yards and three touchdowns in the Chargers’  33-30  win over the Eagles. Took just one hit in the pocket, per the stat sheet.

If it looked like Rivers knew exactly what was coming, well, he did, according to several of the Eagles’ defensive players.

“Phillip Rivers just seemed to know everything that we were trying to throw at him,” said Cary Williams.

“They understood some of our calls or whatever was going on, it looked like he knew exactly what DeMeco [Ryans] was calling to a degree. He knew exactly what we were in to a degree. It was unfortunate. Sometimes you get outwitted, sometimes you get outplayed and I think today was one of those days.”

On the Eagles’ final drive, Chip Kelly could have brought Michael Vick back in the game if he used a timeout.
