You can draft well and still miss the point. The Chargers did plenty of tidy work and somehow never got around to edge rusher, which was the need that mattered most.
The Corleone pick is the one the value grade keeps tripping over. On the needs board they went 1 of 8, with interior defensive lineman the one that mattered most.
Building through the lines is a philosophy, and they stuck to it.
All told, a solid class that does its job everywhere but edge rusher.
