in Ut are often glorified and overranked. They look so much better than they rlly are because they play against very mediocre talent. When they finally do get to the next level, whether thats college or pro, they can't hang with true superstars. If you have an example of someone from Ut who played for BYU who was relevant at the next level, I'd love to hear it.
I'd even open it up to just players from Ut in the NBA even if they didnt come to BYU (although thats what the OP is about).
