You can draft well and still miss the point. The Saints did plenty of tidy work and somehow never got around to cornerback, which was the need that mattered most. It nets out to a B, which feels about right.
The Stewart pick is the one the value grade keeps tripping over. Edge rusher 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.
In sum, a sturdy weekend with one asterisk, the cornerback spot they never got to.
