You can draft well and still miss the point. The Bills did plenty of tidy work and somehow never got around to linebacker, which was the need that mattered most. They moved the roster forward and banked a B for it.
They banked enough surplus on Lemon to cover a lot of smaller sins. Wide receiver was the priority and it is no longer a question, which is most of the job. They came away with juice, if not much beef up front.
In sum, a sensible class that nudges the roster the right way.
