The one they had to fix is still broken. The Bills left linebacker untouched, and that omission hangs over an otherwise reasonable haul. They moved the roster forward and banked a B for it.
Offensive lineman was the priority and it is no longer a question, which is most of the job. Building through the lines is a philosophy, and they stuck to it.
Bottom line, more hits than misses and a roster nudged the right way.
