You can draft well and still miss the point. The Cardinals did plenty of tidy work and somehow never got around to quarterback, which was the need that mattered most. It nets out to a B, which feels about right.
They went 1 of 8 on their needs, which is most of what a draft is for. 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.
