The Eagles have begun their 2016 training Camp preparing for a fresh start under new head coach Doug Pederson.
In moving on from one era to the next, several vets were asked why the old regime under former head coach Chip Kelly didn't work out.
Left tackle Jason Peters, who was named a Pro Bowler three conseuctive years under Kelly, offered his two cents.
"I just think it was more scheme," Peters told reporters Thursday at the NovaCare Complex. "Man it's the National Football League, and if the running back is to the left and you running a zone read, I mean, what you thinking about going to the right?
"It's just, (the NFL) caught up to us.
Peters acknowledged the team's success, but pointed to a change of passers - and their style - compromising the effectiveness of the scheme.
"We had some good years there, back-to-back, and then last year we had our down year," he said. "But we just needed to change a little bit up. Especially with Sam (Bradford) back there. They know he's not going to run it, so kind of put our hands behind our back.
The veteran tackle then indicated defenses progressively gained a better grasp on the plays the Eagles were going to run.
"You can't really blame it on that, we professionals, we got to get out there and they call the play and execute it. But when the guys know, they professionals too, when they know what the play is, it's tough.
Much has also been made of Kelly's up-tempo approach on offense, which is meant to wear down opposing defenses and create opportunities for chunk plays.
Peters, however, saw it working against the Eagles' offense.
"If you run the 100 a hundred times in a row, back to back to back, don't you think the 50th time, you'll be a little slow? But if you get a little bit of rest, you'll be a little bit faster. When you go back to the huddle and you get that wind, you know, you're just a little bit more stronger when you go back up to the line.
Peters before wrapping up addressed the change in personnel that occurred during Kelly's run as coach.
"You know last year, the last couple years, there weren't a lot of vets," he said. "And any vet that stood up and had something to say, you know, we got rid of him. But Doug (Pederson) was a player here, and he understands veteran players and he understands the game, so I think it's better.
