BYU held Kansas St to 9 points
BYU held Arizona to 19 points
BYU held Baylor to 20 points
BYU doesn't win by large margins but they likely still win those games especially the 2 home games. It would be nerve wracking to watch 3 games like the SMU game, but BYU is likely still 6-0
Now something to consider. BYU forcing turnovers will get into our future opponents heads and cause them to play tight and anxious (see conservative) allowing BYU to build leads a different way.
In other words, BYU has other ways it can beat teams as well.
