BYU has shot themselves in the foot a ton against USU. It's not Sitake's fault when the QB throws a lazy pick 6. Or when a punter botches it, or when a player jumps offsides, all of these random little things happen with players just doing something wrong, especially one little thing that changes momentum.
FYI BYU has 2 more losses recently as well. That's prior to the guy you want to hate on. Those other two add into it all and come out to 4 out of the last 9. And they got whooped in those other losses too, so don't make this about your agenda. You're getting way ahead of yourself and turning this into something more.
