Looking at the rules determining the AAC Championship host team, it looks like Temple still has a chance to host the AAC Championship, but does not have complete control over those results. Here are the rules and tiebreakers:
1) Division champion with the best overall record in conference games
2) H2H between the two tied teams
3) Best overall record
4) CFP Ranking
5) Computer rankings
6) Record against common conference opponents
7) Coin toss
Looking at these tiebreakers, it would appear that if Temple wins out, they'll be in great shape to host. The only way Temple would not host if they win out is if Houston wins out, in which case there's no head-to-head to go on, but Houston would be undefeated. Should make an exciting finish to the regular season!
As a side note: none of this speculation matters if Temple doesn't take care of business.
