I get the whole BPA thing, but what if a player of similar value can be had in later rounds? There might not be an edge guy in round 2, but I think a CB or OL will be. If the Bills draft a RB in round 2 after investing a 3rd in Devin last year, I think that would be a poor allocation of draft resources. Same goes for a receiver since they traded their 1st for Diggs.
