Unless the coach is abusing your son you have zero reason to talk with him and even if so, the AD is the proper channel. No coach is going to force an 8th or 9th grader to play on varsity if he or his parents don't want him to, and if he does he should not be in coaching. Save your wind. The parents know who the crazies ones are and the coaches certainly do to and we all laugh at you--doing your kids more harm then good.
just imagining these phone calls from the coach top a BOTC parent
HS Coach: Dad, I wanted to talk to you about your 8th grade son being moved up to varsity
BOTC Dad: Screw off, I don't talk to my kids coaches
three years later
HS Coach: Dad, I got a call from Coach Wojcik about your son
BOTC Dad: I already told you, screw off, I don't talk to my kids coaches
