Sometimes when you try to use reverse psychology it backfires........maybe they told Riley that he was not trying hard enough and that was the last straw for him? I wish him the best!!!! Homesick has nothing to do with it...the kid was a baller!!!!
If that's all it took to "backfire" and make him leave the program then he wasn't the right guy to be QB at UT. All you can do as a coach is to push a kid to help him improve, get the potential out of him. If he shrinks from the criticism then he wasn't the right fit and UTs best he move on.
