Chip Kelly insisted ever since he got the job as the Eagles head coach in January that he will fit his system around his players. That especially applied to quarterback, whether it was an athletic read-option type like Michael Vick or a classic drop-back passer like Nick Foles. Kelly kept insisting that he won with both types of quarterbacks in college, saying often that it’s “a misconception” that he was determined to find one of those neophyte quarterbacks in the draft like Russell Wilson or Colin Kaepernick to run his fast-paced offense. Yet nobody believed him until the Eagles bypassed Geno Smith, E.J. Manuel and Ryan Nassib and went for Southern California quarterback Matt Barkley, a traditional pocket passer. And the Eagles traded up three spots to the first pick of the fourth round to do it. “We’re an equal opportunity scoring offense,” Kelly said. “If we can wing it, we’ll wing it. If we can run it, we’ll run it.” This was the theme of the Eagles’ entire draft. They stayed true to their draft board. It didn’t matter that the Eagles desperately needed help in the secondary in a draft that was rich in safeties as the first four rounds passed by without them selecting one. Instead, the Eagles took tight end Zach Ertz in the second round, a position they were fairly well stocked in, and Barkley at quarterback to compete with Vick and Foles. “There are times you want certain (positions),” Eagles general manager Howie Roseman said. “But that takes away from the process. You’ve got to be disciplined. That’s hard to do, in every round, when you have a depth chart in the draft room and there are empty spots, and maybe you’re taking a player where you have a little depth at that position.
