BYU has a track record in Kalani's tenure of getting some unexpected wins against good opponents, but also losing to some teams they definitely should beat. Because of this track record I expect BYU to end up mostly in the middle of the B12 standings, some years a little better, some years a little worse. In years when they can cut out the head scratching losses they may be able to move up further in the standings.
Hopefully, recruiting will improve enough that BYU can gradually be legitimate contenders in the B12.
