QBASE gave Allen a 62% chance of being a bust.
I would do a Pareto of the negative attributes that led to the assessment. I’d watch film keying in on the most significant negative attributes and look for root causes. For those unrelated to Allen (not running the right route, dropping the ball, etc), I would assess how fixable the problems were.
Whatever issues Allen had, the Bills certainly thought that they were correctable since he was a #7 pick.
I assume that they did the type of analysis I described. Clearly Buffalo didn’t rely on analytics only.
