You can draft well and still miss the point. The Falcons did plenty of tidy work and somehow never got around to offensive lineman, which was the need that mattered most. No fireworks, but a solid B-.
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.
In short, they left a little better than they arrived, which is the whole idea.
