The Kalani years have featured the worst overall record, worst home record, worst road record, worst P5 record, and worst G5 record of any of these groupings over the last 25 years (and certainly since the start of the Lavell Edward era).
By contrast, the Bronco MWC years were the best in every category. This period also had four of the five best teams over the last 25 years. It seems that BYU's path to success is a good coach looking to be the big fish in a small pond.
Flame away!
And Go Cougs!
