I've been playing around with mred's calculator. Here are a few key takeaways I found on the three possible scenarios with ISU being in a 3-way tie for best record. Obviously ISU must win in all of the following scenarios.
- If Colorado loses to Oklahoma St., ISU is IN. No other outcomes affect that. If it's a ASU, BYU, and ISU 3-way tie, the tie breaker will be conference opponent win %. BYU's percentage is so much lower than ISUs they can't raise it high enough regardless of how the other games play out.
- If Arizona St. loses to Arizona, ISU is IN. No other outcomes affect that. If it's a BYU, CU, and ISU 3-way tie, the tie breaker is record against conference opponents and ISU beats out Colorado in this regard.
- If BYU loses it will depend on other games.
- If BYU loses and WV wins, ISU is IN. No other outcomes affect this.
- If BYU loses, and Texas Tech wins:
- If Baylor wins, and Cincy also wins, ISU is IN.
- If Baylor or Cincy lose, ISU is OUT
So the ISU fan guide in order of importance to root for:
Tier 1 (must happen):
ISU (duh)
Tier 2 (any of these teams win ISU is in with a win):
BYU
Oklahoma St.
Arizona
West Virginia
Tier 3 (please god don't let it come to this tier):
Baylor
Cincy
(The UCF/Utah result in no way affects ISU getting in.)
Let me know if anyone sees anything different!
