BYU doesn’t want to kick people out. I’m convinced they do a lot to keep them in. But sometimes, it is pretty hard. A guy gets in trouble. Then he does it again. Then a video comes out of something else. Or, a very DUI.
At some point, the decision is made by the university or the player that BYU isn’t a good fit.
Oregon booted Carrington off their team a few years ago. Yes, even Oregon said we can’t deal with him anymore.
Sometimes it doesn’t work out.
