To be fair not many short QBs before Wilson have done anything. Was Moon Wilson's height? The Bills in fact had suffered through a popular but horrible Lilliputian QB in their recent past. Maybe watching that QB fail while the Bills had a solid roster surrounding him scared Nix away.
Lest anyone think this post means to show support for the unpopular and also horrible but tall QB the Bills had as an alternative, it isn't. It's the wrong thread for that.
