High school coaches despise this guy/others like him because they fear losing control/influence over HS recruits like what happened with HS basketball and AAU. Sark could probably make friends with some HS coaches by not catering to folks like him. That being said, there is value in maintaining contact with this guy and not shitting on him, because it's not just him, he has other elite level trainers working out with prized recruits at his facility too.
FWK's model (among others) is to get paid from NFL athletes and parents of less talented hs players. While I'm sure it would be welcomed and could have happened in the past, he doesn't need bags of cash from universities. Just let him come on campus every once in a while, and don't shit on him and we should be fine. We are aligned somewhat with FWK in the respect that he wants his guys to develop and then come pay him once they make the league.
