I completely agree that it won't happen this year. Even if Hawaii lost, BYU would still probably miss out on an at-large bid this year. If Hawaii wins, that would make it even tougher.
I'm just saying that theoretically, in some year, there could be more than 1 non-BCS team. There is no rule that says that there can be only 1 team, only that just 1 team can qualify automatically.
