Well, if they're going to have years of this ahead of them...why would you give a damn about them in their first year? If they are life time cheaters, boom...they win. We can't solve that. It takes a lot of strategy to manipulate a season (nonetheless, multiple consecutive seasons). That guy can have at it all he wants. That's just who he is.
Nothing you said makes me think sitting self rates from playoffs is anything but a good idea. What I don't want to see at 4.5 Districts is a legit D1 roster squaring off with all players, coincidentally, in their first USTA season ever. And then that team can't play at Sectionals because half the squad got DQ'd.
