I must be crazy or something.
Bray is your best QB, and from what I've seen, it's not even that close. Why not play him? Yes, I know, he's going to get hit. Yes, I also know that the Memphis version of Bray isn't the guy you're going to see the whole year. I'm just not big on having one QB, who is of a lesser talent, act as more or less of a shock absorber for the guy that you know is going to be the starter later.
Why not just give him the nod at the start, and let him get a full season under his belt as a freshman?
