First of all, congratualtions to your son on his offers.
It is very hard to advise you on which situation would be best for your son. I understand that your son will feel that he might make the wrong decision and be sorry for it later on down the road. He needs to go with his "gut" feeling.
You seem to have left the decision to him, though you prefer that he remain closer to home, which I always feel should not be the main factor is choosing a school. I do feel that this is a decision that should be made together.
One thing I would like to point out that should be considered. I am finding out through many posts on this board, that many coaches are not true to their word and many seems to come and go. Deciding to attend any school should not be based on promises, rather where he will get a chance to play regardless of the coaching situation.
Hope this helps a little.
