Nothing to add to all the good advice posted. I will just reiterate the "TPM" comment; he needs the opportunity to mature and develope. IMO, in the long run, he will have more opportunity to do so "playing" at the JV level. Too many Freshmen are either thrown into the game (you need game competition but you don't really have the opportunity to enhance specific skills while playing)and don't really get better skill-wise, or worse yet, end up with a lot of bench time and you certainly don't get better that way.
He needs to be playing. Quite frankly, the H.S. team experience often doesn't play a huge part in his future opportunites (that can vary regionally). Making Varsity at the Freshman, Sophomore or Junior ages doesn't necessarily affect his College opportunity.
