And I would argue that they are incorrect. Instead, I would say that BYU dominated Utah from 89-92 (102 point difference) and from 93-01, it was 5-4 for Utah with a point differential of 0 (very close!) and then from 2002 on, Utah has held a strong advantage with a 137 point difference and a 13-3 record. So it's almost like 3 eras (although the 89-92 era was just an extension of the 72-92 era where BYU was crushing Utah regularly).
I guess that's my point in identifying a random window of time. It represents an era of Utah success. I'm not trying to be a jerk about it. it is what it is.
