In response to the rule RheaCo brought up: I have never heard of such a rule. In saying that, I'm not saying its not true; it's just an awful rule to have in place. Granted, I believe if a player starts a season, especially if he goes through all of summer workouts, he should finish. That's how I was raised, but that was many decades ago. If he wants to concentrate on basketball, more power to him. He is a decent basketball player, and I'm happy to hear that he has some small schools looking at him.
As far as replacing him at Y, could they move Stone into his position? I would think JT knows the system well enough to jump right in. He is a versatile athlete who, I would think, can adapt to the role at Y really quick. Just an observation from an old man who loves the game.
