My take, for what it's worth.
Never put all of your marbles in one bag.
It's ok to set your goals high, but, have a plan of action if number one does not work out.
He needs to be on the road to the prospective schools (plural) to meet the coaches and take a look around - now.
Bottom line the prospective coaching staffs need to see him play - period.
Check into summer camps and showcases at the schools he is interested in, summer ball is ok but he needs to get to those prospective colleges to get in front of those coaches.
Coaches I would think may remember a one on one, face to face meeting much better vs a phone call, email, or letter.
