To me, Howell, Corral, and Picket don't appear to be any better prospects than Book at this point. The coaches have a big advantage over us, they have seen book practice and know his strengths and weaknesses. If they don't think Book can make a competent backup, they should cut him now and grab someone in the 4th.
Pickett is far, far better than Book as a prospect. It's not even close. Pickett is basically ready to start. I'm not saying he's better than Winston right now or he's a franchise QB.
