it had been much easier to transfer credits from Dixie College to Utah than to BYU.
BYU and Dixie started working better together and things seemed to start moving toward evening out during the beginning of Bronco's most successful period. Then, with the cool factor associated with BYU hiring a Polynesian coach, I'd say it's evened out.
BYU tends to have a majority among the more educated and white collar types and Utah tends to be favored by blue collar types (although there are plenty of exceptions to both).
