I don't even want to worry about the tie breaker stuff. On paper BYU should be able to sweep the next three. But, there is a reason few teams go undefeated. Winning is hard. Luckily, BYU had two byes in the right spots.
• uu game will be unpredictable, but very winnable (uu has no offense)
• KU at home feels winnable (KU has 2 wins this season)
• @ ASU will be a challenge. BYU's up for that challenge.
• Houston at home is pretty much a guaranteed W at this point.
