PHILADELPHIA (CBS) – The Eagles wrapped up a perfect 4-0 preseason on Thursday night with a 28-10 win over the Jets at the Linc.  Next up is the regular season opener on September 9th in Cleveland.

So what did we learn about the Eagles this summer?  On the positive side, rookie quarterback Nick Foles announced his presence with authority, shining in extensive playing time while starter Michael Vick battled injuries.  And the defensive line can get after any quarterback almost regardless of who is in the game.

But their are lingering concerns at linebacker and at left tackle.

KYW’s Matt Leon spoke with Comcast Sportsnet analyst Ray Didinger about what he saw from the Eagles in the preseason.
