bballman,
That's a nice problem to have, congratulations to you, and especially your son. All of his hard work is beginning to pay off. I don't have much to add, you're receiving very good advice from people that have been in your shoes. I will say that my son chose to attend the school that offered the least amount of scholarship money. They had a large incoming frosh class the prior year and most of the team is returning for 2012, so they didn't have much wiggle room. We felt they were genuinely sincere in their interest for my son, and they had all of the important factors we were looking for from an academic and baseball standpoint.
Once bballkid makes his decision, please share the good news with all of us...we're happy for you!
