I believe that if BYU wins, ASU loses, and Colorado or ISU loses, then BYU
clinches a spot in the CCG, or at least the probability of them not making it becomes minuscule. The ASU loss is more important for BYU than the ISU or Colorado losses, since ASU can still beat BYU head-to-head next week, at their place, and therefore own the head-to-head tiebreaker in a 2-loss scenario.
Regardless, go Buffs!
