undefeated. Likewise, Arizona St. could win out and Iowa St./Texas Tech could still be undefeated. But the likelihood of 2/3 of BYU, Texas Tech, and Iowa St. being undefeated at the end of the year is rather small (0.2% according to FPI) so I would argue that any of the 1-loss teams winning out will be at worst relying on tiebreakers to get into the CCG.
