I really liked Gailey, and the offense would’ve been great with Allen. But Gailey’s problem was that he didn’t give a crap about defense and fielded some of the worst defenses in Bills history. No way they make the playoffs with those defenses.
Marrone fielded some great defenses, but he and Hackett would’ve ruined Allen before he got off the ground. He would’ve been a first round bust, IMO.
I think the best would’ve probably been Ryan. If he could go 8-8 with Taylor, imagine what he could do with Allen.
