Two cents worth of advice--take a step back and take a close look at each school he is interested in WITHOUT baseball in the equation. If he is injured walking out of the dorm on the first day of college in the fall, or if he decides he is sick of the hard work and commitment, or if a young lady attracts him and he chooses time with her over time with baseball, where would he want to be?
Now, if baseball is the overriding consideration, and he is either a genuine pro prospect or has a driving passion to be a part of baseball at the higher levels in the future as a non-player, bring baseball back into the equation and figure out the balance between the school he likes best with baseball and the school he likes best withtout baseball.
