your rival against the same opponents, great. BYU went 2-2 in the stat that matters. Utah went 3-1. Your cute little "but but but if BYU would've played them at home things would've been different!" rant is pointless. Do I wish BYU would've played Michigan or UCLA at home? Of course! But the facts (not silly what-ifs) are Utah went 3-1 and BYU went 2-2.
If it makes you feel better to justify why BYU is really just as good as Utah and they are just lucky to play 7 home games, fine. 3-1. 2-2. Period.
