You just really need to be patient and let the the velocity catch up with the talent. Though talented, your son is still young and I believe most P5 coaches need/want to see velocity in the high 8's before moving forward. A few years back my son's velo at 15 was low 80's. - Consistent work and development led to low 90's the summer prior to his senior year - while it may seem like power 5's aren't recruiting rising seniors, there were still Power 5 offers to be had.......so be patient........you don't need to make a decision until you have to make a decision.......if i could do it over i would have spent a lot less time plotting a path and more time enjoying the ride.
