I think it's a possibility that the PAC12 takes from the Big 12...but I do think it's more likely that the Big 12 takes from the PAC12. In that case, we're fine.
I also think it's possible that if the PAC12 DOES end up taking from the Big12 that BYU will be a target. Objectively speaking, BYU is one of the better additions that the PAC12 could get from that conference and I think they may be less picky/arrogant/snotty now that they're desperate. Let's remember that the Big 12 also continually said no...until they got desperate and threatened with extinction. It changes things.
