It’s simple, if they are comfortable starting Allen then create a game plan with a heavy running game, some short stuff and the occasional play action bomb. That’s all they have to do if they want him under center.
I’d have a hard time believing that scenario would give the Bills any less of a chance than it would with one of the other bozos out there. Executing a limited game plan would be better experience than sitting on the bench behind two guys that don’t know what the hell they are doing.
