That really isn't the problem with D.Inglebary. The problem is that when he is in, the Bills cannot threaten the edge with the run. He has consistently failed on really standard NFL play designs for the running back to get to the edge. He does not have the speed to threaten the edge, and this has a cascading effect that crushes the middle of the field and more importantly the pocket when he is in the game. He does what he can, and bless him for that. With a college-dominant OL and operating inside the tackles his sharp cuts are amazingly effective. But he limits an offense.
