One week time frame is very typical. He needs to go where he thinks or has been told he will play. 12 RS sounds like a lot. It's one thing to compete for a shot, but another if he has little to know chance from a talent stand point. How does he measure up against current rooster and other incoming recruits.
Its still early, find a school that he loves nd they love him back. It does no good to go to a DI and sit the bench at a school he doesn't like. Good luck!
