“He was the best player on our board” - how often have you heard an NFL GM say that after the draft? Quite often, I’d imagine, as this is a pretty common way of justifying a pick after you made it. But unlike the Cowboys, who leak draft boards left and right, we have no way of checking those GM’s big board to verify their claim.
What we do have, however, is a consensus big board, which makes it fairly easy to check how a given team did in the draft versus the consensus.
