You can draft well and still miss the point. The Bengals did plenty of tidy work and somehow never got around to cornerback, which was the need that mattered most. For now it grades a C+, with the swing picks left to settle the rest.
They are betting Umanmielen proves the room right and everyone else wrong. Building through the lines is a philosophy, and they stuck to it.
In the end, one you will need a couple of seasons to truly judge.
