If Taysom had gotten hurt in 2014 but stayed healthy in 2015, we would have finished at least 11-2. If Riley had stayed healthy in 2012, we would have finished at least 11-2.
We had mostly healthy QBs from 2005-09 and then really bad luck with QB health from 2012-15. If those scenarios had been reversed, I wonder if Bronco would still be at BYU.
