We have seen that thought before that the Y dominated the MWC. I seem to remember that up until Utah left, Utah, TCU, and the Y each had an equal number of championships and CSU had 1 fewer. It was pretty much 4 teams equally sharing the titles. The Y was dominate before McBride came in in the early 90s, they just need to update thoughts with the last 30 years of history.
Someone on that thread pointed out that BYU didn’t dominate the MWC. Even in years when BYU won the conference they weren’t as dominant as Utah and TCU were when they won.
