Does you son's travel team have relationships with any the schools your son is interested in? Will there be, or is there a reasonable chance coaches from the schools your son is interested in will be at those tournaments? My son attended 4 college camps in the fall and Feb. In each case he had been in contact with the RC, and his summer team coach had been in contact with the RC. I do think it's a waste to attend college camps blind so to speak.
My son is a 2020 and everything he'll be doing this summer is based on getting in front of the coaches he needs to. He's scheduled to play in the 17U and 16U WWBA, but knows that may change based on how his summer is going and if makes more sense for him to stay local.
