If you actually started running scenarios the 3-loss teams are probably mathematically eliminated as well because there just aren't enough losses to go around above them so goodbye Illini and Huskers.
The two-loss teams (MN, NU, UDub, UCLA) are very much in it mathematically but as a practical matter they are out because they just need too many things to go their way.
Challenge accepted (just for the fun of it, i know its not gonna actually happen)
1. What needs to happen for Illinois to make the CCG
ILL wins out, goes 6-3
IND wins out, goes 9-0
OHIO St loses out, goes 5-4
MICH loses all games except beats OSU, goes 6-3
USC beats Iowa and beats Oregon, loses all other games, goes 6-3
Iowa beats Oregon, loses all other games, goes 5-4
Oregon beats Minn and loses all other games, goes 5-4
Minn beats NW and loses all other games, goes 5-4
NW beats USC and Mich, and loses all other games, goes 5-4
Wash beats Oregon and UCLA and loses all other games, goes 5-4
UCLA beats USC and Ohio St and loses all other games, goes 5-4
Neb beats UCLA and Iowa and loses to PSU, goes 5-4
So ILL, Mich, USC finish in a 3-way tie for 2nd at 6-3. And Illinois wins that tiebreaker (I think)
2. Ok Nebraska is harder to figure out because they have lost to USC, Michigan, and Minn. My goal is avoid any tiebreakers between Neb and any of those 3 teams.
Neb wins out, goes 6-3IND wins out, goes 9-0Mich loses out, goes 5-4Ohio St loses all games except beats Mich, goes 6-3USC beats Oregon, loses all other games, goes 5-4Iowa beats Oregon and USC, loses all other games, goes 6-3Oregon beats Minn and loses all other games, goes 5-4Minn beats NW and loses all other games, goes 5-4NW beats USC and Mich, and loses all other games, goes 5-4Wash beats Oregon and UCLA and loses all other games, goes 5-4UCLA beats USC and Ohio St and loses all other games, goes 5-4ILL beats NW, and loses all other games , goes 4-5
So Neb, Iowa and Ohio St finish in a 3-way tie for 2nd place, and Neb wins that tiebreaker (I think)
So, as unlikely as these scenerios are in reality, I believe Illinois and Nebraska are technically still alive.
