Different people learn better differently. What if he's the kind of guy that learns better and understands more by doing? Would make no sense to sit him and slow his progress.
Like it or not, Josh Allen is THE most important player on that roster. Every decision made needs to be revolving around his development and his progress. If we play a raw rookie and suffer a 2-14 season...so be it.
But look how this team is shaping up. We are going to be a run first team again. Shady and Ivory. Strong defense. I think in the right set up Allen could play and we could do just as well as if AJ played.
