for him. Have to look at both sides, not just BYU.
ASU will lose a senior after this year sure... But then they'll have two seniors competing for the spot next year, if both stick around. One is former #1 QB Blake Barnett. The other is a highly rated 4 star. Then there's a RS freshman who was a top 15 QB prospect.
BYU will have a senior Hoge, a RS freshman or soph Wilson, and then Hall if he sticks at QB. If I'm a kid going solely on who I think I can beat out and get PT, I'm going BYU. We don't have a glut of QBs.
I don't like missions but I'm actually all for it in this case. If he's between the two, neither make a ton of sense for him if he wants to play immediately.
