Yeah, Herm isn’t an upgrade and neither is Christobal. Sumlin is only an upgrade of you believe he can elevate their recruiting, but he’s not a better coach than Rich Rod. UCLA is an upgrade for sure and I think it’s far too early to know whether Jonathan Smith is an upgrade over Gary Anderson at Oregon State.
Sumlin has never left a team better than he found it. There's way cheaper options that have a good chance to improve the team.
Sumlin would provide instant recruiting improvements, perhaps setting it up to win in 4 years, under a real coach. I can't see UofA wanting that, but like so many, they don't seem willing to peel that onion.
Sumlin replaced a 5-year run of Briles at Houston, and maintained success.
Sumlin took over an aTm team and won 11, followed by 8, 8, 8, 7. That's called getting steadily worse.
