Taking the rivalry game aside, compare the performance of the two teams relative to other high mid to high level teams. Since going independent BYU has 1 win over a P5 team with a winning record (7-5 Georgia Tech). Byu has a couple solid wins against Boise, but otherwise they have consistently lost to top 40-50 teams. Utah isn’t elite by any means, but they’re fairly consistently a top 20-40 team now. Byu has been 50-60, and fell off a cliff this year down to ~100. I’m not trying to prop up Utah. They are a middling P5 team. It’s the same size gap between BYU and say Arizona State, Iowa, UCLA, Mississippi state etc. I don’t see BYU staying around 100 in the rankings, but I also don’t see much hope of being much better than 50-60 anytime soon. In my opinion the difference between a team that is in the 20-40 range and a team in the 50-70 is quite significant, and that is how I see the two teams now.
