I was thinking about this too. A player like Josh Allen hides flaws in an Offensive system, because he uses his athleticism and freakishly strong arm, to make plays that otherwise wouldn't be there. If nothing else, Keenum running this system, even if it is only in practice, may help the coaches see flaws that were not noticeable before. If that is the case, and I honestly don't know if it is or not, they would have to start scheming guys open, instead of relying on Allen to make something happen. Although obviously not ideal, I believe there could be some good that comes out of this.
