From playing time against the Panthers to the D-Line rotation to new WR Jeffrey Maehl, here are three Eagles practice leftovers.

The key number when it comes to his job: 1.95.

That was the overall grade the Eagles coaching staff gave him for Friday’s performance against the Patriots. It was the highest mark out of all the offensive linemen. Johnson explained the scoring system on Tuesday afternoon.

“I think 2 is the best you can get,” said Johnson. “Basically every play they have a scoring system. It could be a zero, which is pretty much total failure, and then I think three is being the most dominant you can. Twos and threes are good numbers for every play, so that’s how they grade ’em. I think I had a few threes, but mostly twos.”

Nick Foles saw five defenders in the box, and so his decision was simple: hand the ball off to Bryce Brown.

Matt Barkley got a 2 vs. 2 matchup he liked on the perimeter, and so he threw the screen outside to Greg Salas.

The play-calls were exactly the same. Yet the quarterbacks made two different decisions, both which resulted in touchdowns.

We talked about run-pass options in this space over the weekend. And Grantland’s Chris Brown explained them further in his terrific piece about Chip Kelly’s offense. After Monday’s practice, we caught up with several players to gain a better understanding of the “packaged play” concept.

The Eagles’ defense tried its new 3-4 scheme on for size Friday evening, and learned that it’s not yet ready for prime time. That was evident on the first play from scrimmage — a 62-yard run up the gut from New England’s Stevan Ridley. 

The Eagles have acquired WR Jeff Maehl from the Texans in exchange for offensive lineman Nate Mankin.

Defensive coordinator Billy Davis has a philosophy when it comes to rookies.

“I believe that when they start they should start at the bottom, and they should earn their way up,” said Davis. “It doesn’t take long for the better players to push their way up. Really, it comes from basically saying, hey the vets have been here and worked at it, someone has to take it from them before you just anoint somebody. But a lot of times when you see the talented young guys come up, they take it pretty quick. And when it’s time and you’ve seen enough and they’ve earned it, then you move them up.”

For the record, Davis hasn’t moved Earl Wolff up just yet. But he did have him working with the first team opposite Patrick Chung for the entirety of Monday’s practice.

Let the record show that one of Chip Kelly‘s first decisions as head coach of the Eagles was to sign Cary Williams to a three-year, $17 million contract.

The deal has upwards of $10.5 million in guaranteed cash (The $4.75 million base in 2014 reportedly becomes guaranteed on the fifth day of that league year.)

Kelly knew he wasn’t buying the services of a “yes” man  or a choir boy with that money. He was getting an edgy, hot-tempered corner that would essentially serve as the anti-Nnamdi (even if Williams said he modeled himself after the Raiders version of Asomugha at his introductory press conference). The team needed players in this secondary that wanted to hit people; they needed to extract the soft and fill in the holes with concrete.

Lane Johnson has spent the past three-plus months fine-tuning his technique and preparing for life as an NFL offensive tackle.

Friday night was the first chance to see how he measured up. And the Eagles’ No. 4 pick produced impressive results.

“I thought Lane did a real nice job, especially in a first game,” Chip Kelly said. “Very consistent. He may have been our most consistent offensive lineman, the way Coach [Jeff] Stoutland graded it out. Knew exactly what he was doing, didn’t have any mental errors, plays with great effort. He’s always trying to make the extra play and play until the whistle.”

During the spring, tight end Clay Harbor spent some practice time at outside linebacker.

Today, he was at a different position: wide receiver.

“We know we’ve got seven tight ends, and he already knows how to play inside because all of our tight ends know how to play the slot,” Chip Kelly said.

Cary Williams says that the Patriots came into the joint practices with the Eagles talking trash. He claims that they were doing some “dirty things” on the field. And he didn’t want them to get away with it. Not in the Eagles’ back yard. So he got in a dust-up with rookie receiver Aaron Dobson when the teams went head-up during Tuesday’s practice, and was promptly removed from the session by head coach Chip Kelly.

“They came in there talking. They had a lot of jokes and he-hes and laughs. A lot of dirty plays going on,” said Williams, who returned from a hamstring injury Sunday. “There was a reason behind what I did. There was a reason behind the madness. At the end of the day I still have to do things the way coach wants me to do it, and I understand that, but it definitely would have been a different situation if it was Baltimore. It wouldn’t have been a fun practice for the Patriots, I’ll tell you that.”

Here’s what we saw from the Eagles’ defense after having reviewed Friday night’s game against the Patriots. Notes on Vinny Curry, Fletcher Cox, Jake Knott and others.

The Eagles offense did something on Friday night that we have seen very little of during training camp. It huddled.

Chip Kelly has had his group working at a frenzied pace during practice, with the idea that the games will seem slower by comparison. When Matt Barkley came into the game, the pace was slow by any standard.

“I think he was just trying to start slow,” said Barkley, “but he eventually got excited and went up-tempo and we all felt better for it.”

Chip Kelly said after Friday’s game that his up-tempo package is just one of many tools in his toolbox.

The truth is, it’s likely to become the foundation of his offense. It’s what Kelly had so much success with at Oregon. It’s what the Eagles have been practicing all offseason long. And it’s a style that other NFL teams are already having success with.

But as we saw Friday night, there’s more to it than just tempo.

Here’s a review of what we saw after reviewing the TV tape.
