2011 (7 turnovers) and 2015 (5 turnovers) are the most prominent examples, but even in other years like 2012, 2016, and 2018, Utah's defense has scored TDs on their own that proved to be the difference in games with 1-score final margin-of-victories. It's been absolutely maddening how many times during the 9 game losing streak that Utah's defense has scored TD after TD in this matchup to clinch wins for them, whereas BYU's defense hasn't done it since the early 90s.
