KSU
Baylor
Kansas
UCF
UU
BYU owns a 3-0 record versus these 5 common foes. ISU is 2-0. Colorado is 2-1. Every one of these 3 top teams has beaten Baylor and UCF. BYU beat KSU, but Colorado lost against KSU.
None of these 3 top teams play each other. So most likely the winning record percentage against common foes will decide who goes to the conference championship. BYU has the edge at the moment with wins over 3 of these foes.
Actually, BYU owns the next tiebreaker with Colorado as well at the moment because we beat the common foe highest in the standings (KSU), while Colorado did not. If KSU gets passed by Baylor in the standings however, this tiebreaker might be nullified. [Note edit: This assumption was wrong. Tiebreaker goes down the list of common foes so KSU would likely still matter and be the tiebreaker.]
What this essentially means is that BYU can almost lose any 1 game and we can still go to the conference championship provided KSU keeps a record better than Baylor. However, the most important games left on the schedule are to beat Utah and Kansas.
All of this gets thrown out if we lose 2 games. It gets much more difficult in such a scenario to stay ahead of the pack.
This is my assessment of the tiebreakers. Let me know if you think I'm wrong.
