In fact, that is oddly a weak spot for the league. Pretty odd as well. USC should be better at it every year. When UW was good at it, they won the league 2x. I could see Utah still being pretty good at it. But not the depth from 2019, or edge talent. But still really solid.
Like I said, this matchup often decides the game because that unit forces BYU into some bad TOs. If they win the LOS battle, Utah wins.
