That's your answer right there folks.......it was bad timing for the Bills (which is natural because there would never be good timing for the Bills). They had a brand new HC and no GM and that is not the time NFL teams to go all in on a new franchise QB.
Ironic, because if it was 20 years ago they might have said, hey, WTF and drafted him. But now, drafting a QB is a career and franchise altering decision so it's not going to happen without a whole bunch of people all in agreement on the plan.
