One thing that is beyond dispute: The Eagles need more production from their front four if they hope to make any significant gains on last year's lackluster campaign. It's not that the pass rush was bad in 2016. It just wasn't good enough to stop opposing defenses from marching up and down the field at will over the back half of the schedule. Some of the blame goes to the pitiful play at cornerback that the Eagles got; quarterbacks like Kirk Cousins and Andy Dalton were taking three steps and firing at will. At the same time, Troy Vincent and Bobby Taylor aren't walking through that door. Ronald Darby looks like he could be half of a passable rendering, but that still leaves the problem 50 percent unsolved.
