my very uninformed perspective on this, especially given that this is one year where actual roster slots for games are valuable, is that he is not real comfortable with anyone at PG after Collinsworth.

I think either Chatman or Toolson will redshirt and my understanding is Jordan Chatman has been injured quite a bit this summer. That injury for an RM has likely impeded his ability to get into any playing shape and if not fixed could develop into a lingering and more debilitating injury. He seems like a good candidate to redshirt.
