Utah is a gay PAC PAC PAC tryhard team, so they'll obviously be motivated but they have a lot going against them, even more so than in 2018/19:
1) They're beat up, have regressed over the season, and looked like ass against a soft Oregon team.
2) No defense compared to last year.
3) Their quarterback has played bad most, if not all year.
4) SC is more motivated by the home town cooking they received in SLC and should insert the plunger.
5) Utah does not have the skill players to beat SC twice, this time on a neutral field.
I don't think Yoot have much of a chance against USC.
Regarding their Gayness, it's important to remember that Utah has been a more successful program over the past 20 years than the following schools:
Oregon State
WSU
Arizona
Arizona St
Cal
UCLA
Colorado
They also beat Nick Saban.
Those other teams didn't get to beat up on mountain west teams for 20 years.
