First priority would be to go where he is wanted the most and where there is a plan for him,and of course which is the best fit for him overall. (academics, program, location, cost, etc) . I know the Texas schools are well scouted but not sure about the others. It really depends on the school and the program, is it at the top or the bottom of their conference ? Is it a program that has kids drafted? All of this is available publicly.
My so pitched at his SCAC school's pro day and there were over 30 scouts in attendance, but frankly I am not sure this is an area you need or should explore with the coach, I would be more worried about his chances of making the travel squad first. I know at my son's program not many Freshmen play so I would be more worried about this first. If he has the talent he will be noticed if he is at a successful program.
