Unless I missed something, did anyone in Utah’s AD or any actual university representatives say anything that “bad” about the Big 12 outside of denying rumors (which everyone was)?
It seems the butt hurt against Utah is because of their vocal fan base on twitter and that’s about it.
Now on the other hand, ASU was very vocal even the day after the merger about how they didn’t want to go the Big 12.
Utah’s head coach bemoaned the Big 12 after joining by saying that they’ll be gone in 2-5 years.
But your overall point remains. Most of the administrative flames came from ASU.
