BYU has known about the kid forever...I don't think they really are. Wouldn't shock me if on some level they are happy he is taking his talent elsewhere.
And if we're going to talk math...of course they are going to see more and more "slam dunk" recruits (Which is about the stupidest term I've ever heard) because there are a lot more of them. Still only 25 schollies a year but Mormon family trees don't have one branch. There will continue to be more and more players with some connection to BYU. Some connection doesn't imply obligation. It implies only that there is a connection. That's it.
