Utah does not have a fanboard as robust as and interactive as CB. BYU wins that one - hands down.
But some better questions…which fanbase is more arrogant? BYU.
Which fans are more self delusional? BYU.
Which fanbase has fatter wives? BYU.
Which fanbase overrates their self importance? BYU.
So BYU comes ahead on those points too - touche. Lots of winning for BYU fans today.
