His contributions as a player are great, but that's where it ends. As a coach, he's gone way beyond what a rival coach
would normally in trying to hurt BYU football. His petty belittling and dismissing of all things BYU through his long coaching career are ridiculous. And as soon as Utah got a leg up on BYU with their Pac12 inclusion, he was very much on board with the efforts to marginalize BYU. Kyle would have to start singing a very different tune before BYU could ever really welcome him back into the fold.
But I don't think Kyle wants in at all. I think he actually hates BYU.
