Why would the teams in the premier want to set up a model like this? It guarantees 4 or 5 of those teams are 6-6 or 7-5 at bestB1G Premier Division and B1G pathetic Division. Best team in the Premier division is crowned champion and gets auto playoff birth. 2nd and 3rd place play for the second playoff spot. Best team in Pathetic gets to play in some sort of Rose bowl type game. Bottom two teams in premier get relegated to pathetic division next year. Top two teams in pathetic division get promoted to premier division next year. 2 Protected rivalry games for each team. Add in Notre Dame eventually.
Premier:
Michigan
Penn State
Washington
Ohio State
Oregon
(Notre Dame)
USC
Iowa
UCLA
Pathetic:
Minnesota
Wisconsin
Maryland
Rutgers
Purdue
Illinois
MSU
Nebraska
Indiana
Northwestern
It subsidizes the bottom teams financially without the benefit of beating them
If it went to a model like that there would be a full split
