It isn't almost, it is a zero chance.If CSU gets to the MWC championship, there is almost zero chance UNLV goes to the playoffs. With the assumption BSU gets to the MWC championship game, even a bad loss to CSU wouldn't drop them below UNLV.
The Auto G5 spot has to be a conference champion. Which is why we would get the nod over Boise if we beat them, regardless of head to head resumes.
The only other way is to get an at large. which would mean us being ranked basically in the top 10. That isn't happening with going 4-0 the rest of the way. So if CSU gets in the Champ game, we are out.
Time to root against CSU!
