I've always observed and said that the main difference between the fan bases is that most BYU fans root for (or at least smile upon) Utah when not playing BYU, while most Utah fans root for every team that plays BYU. It is CB that is the exception to the norm - where most of the truly FANatical BYU lovin' - Yewt hatin' diehards are found. However, I acknowledge that blue-goggled view probably reveals my bias. The rank-and-file Utah fan may see that description as flipped on its head.
