If Hawaii beats SDSU at home this week (which I guess is about a 50-50 shot), then Hawaii wins the Pacific division and plays in the MWC championship.
Then if Hawaii were to win the MWC championship, then they would qualify for LV bowl.
Maybe also if AAC really really wants to keep a team in Hawaii instead of being shifted to another bowl, then maybe Hawaii would have to go to a bowl on the mainland. AAC has a contract with the Hawaii bowl. But I doubt that happens.
