This is a concern of mine too, but is a few years away. My guess is that Moss plays some PG while Dickerson sits. I don't see Fleming as the PG type but I guess he may have to. Obviously the other plan is to bring in someone in the '16 class or juco. Keep in mind Fran did have a plan, but that plan left for Kentucky.
I feel like Jok will be ready to handle that his senior year. Marble did something pretty similar at times.
