This is what I suspect the underlying feelings of fanbases who have switched conferences are. Almost all of them would they're happy, or that they "had to do it" because that's what we do as fans (we do the same).
Legitimately excited: Texas, BYU, Cincy, UCF, Houston, Arizona, Colorado, Oregon, SMU, Louisville
Tell you they're excited, but secretly hate it: Nebraska, Oklahoma, Mizzou, Maryland, A&M (now that Texas joined - they were previously legitimately excited)
Honest about it being their best option, but not overly enthused: Arizona State, WVU, Rutgers, Pitt, Cuse, USC, Washington
Openly hate it: Utah, Cal, Stanford
