If college coaches shouldn't recruit 9th and 10th graders than High School coaches shouldn't bring 9th and 10th graders up to varsity either. I think both the HS and college coaches have a pretty good idea of who is going to develop into a good player.

Over the years there have been plenty of HS Junior and Senior recruits who did not become major contributors at the college level. Transfers are nothing new and kids hanging it up didn't start with early recruiting.
