How does that compare to other teams and coaches in that same period? (I don't know.)
I think some people are down on Kalani because of recency bias, i.e. mainly because last year was a particularly bad year, and despite being in the Big 12, OUR expectations were not low, and IMHO an average BYU team could actually have done very well against last year's schedule.
The sports gods are fickle. I will wait a year to pass any judgement.
