I think he wants to go to BYU.

1. He likes how BYU gave his bro opportunities and development.

2. If he had been serious about other schools, he would've (and could've) put in the work to get some more prestigious offers.

3. Also, gotta believe the PAC being in disarray doesn't help those schools' chances.

4. Also, Oklahoma State is a good option, but I don't think it is a cultural fit or a sure bet the way BYU would be.

I am not even sure how bad BYU wants him (seems like would be a great get), but I am guessing they're the front runner.
