Lots of reporting on what happens if there's a 2-, 3-, or 4-way tie atop the standings... but what happens if:

1. Only BYU wins (other 3 lose)?
2. Only ASU wins (other 3 lose)?
3. Only COL wins (other 3 lose)?
4. Only ISU wins (other 3 lose)?

In each case, who would be the 2nd title game participant?

Also, what if all 4 lose (and there are a ton of 3-loss teams). Who plays then? I know it's ASU/ISU if there's a 4-way tie, but the math probably changes when more teams are added to the mix.
