Some of you are also forgetting that along with the new offensive system, Philly is also getting a new defensive scheme this season. They're converting from a 4-3 to a 3-4 most likely.
The 3-4 defense vs. the 4-3, and how the Eagles fit
It takes a couple of years for ANY team, not just us, to make that switch. Their defense was a mess last season, so they have very little talent carrying over as it is.
They might be a mess on BOTH sides of the ball, at least for the fist half of the season until they figure out what that "innovative" college coach is doing.
