BYU was fortunate to beat Nebraska, BSU, and SJSU, and unfortunate to lose to UCLA and Mizzou. You want to keep all those good breaks, and eliminate all the bad breaks.
Sure, under certain circumstances, BYU could have easily been 11-1. But under different circumstances, BYU could have also easily been 6-6.
We were actually closer to 6-6 (or at least 7-5) than to 11-1.
