If I were him, I'd take that job. Get paid, easier competition. They'll still be in a semi-decent conference, even if it's the Pac-10 again. If B1G raids, then they'll be in some variation of the Pac-8/Big-12. It's not like recrootin is his strong suit anyway, he's just gonna do the instate thing in AZ like he did in MS, they have 26 prospects there compared to our 31 in the Sip. After that he'll just fly to LA or Dallas/Houston and get some leftovers.
Coaches' shelf live is like 10 years so who really cares what conference they are in come 2032.
