He sent an email to the conference to get some clarification but essentially he's saying if we have 0 losses we're obviously in.
With 1 loss and there's a 4 way tie with BYU, ISU, KSU, and Colorado...the only common opponent is Kansas. So it'll be super important to win that game. Assuming we all beat Kansas, we look at strength of conference schedule and KSU wins that. At this point Casey is assuming the tiebreaker rules reset and you run through the same steps with the 3 remaining teams (this is what he emailed the conference to get clarification on) and at that point BYUs win against KSU qualifies them to advance to the CCG because Colorado and ISU (in this scenario) lost to KSU and KSU is the highest rated common opponent amongst the 3 remaining schools in the tiebreaker.
With 2 losses it's pretty much chaos. Way too many scenarios to go through, but you need ISU, Colorado, and KSU to all lose twice too, which is highly unlikely.
SO....the takeaway here is that if BYU only loses once for the rest of the season and that loss is not against Kansas then we will make it to the CCG.
Feel free to listen to the podcast to get the full detailed breakdown. There are a few tiebreaker rules that I skipped over in my summary since they weren't applicable
