A team that finishes 7-5 with the 40th toughest schedule likely has accomplished as much as the one that finished 8-4 but whose SOS was #65.
It’s early in this season but UU and BYU have the same record but BYU’s schedule has been tougher. Because it began the season so far down on Sagarin’s rankings, it lags behind even USU.
Using the SOS properly gives BYU credit for its accomplishments.
