Two BIG divisions of ten, which would keep the name Big Ten still relevant as far as divisions. We could go straight up East/West with a nine game round robin division schedule with championship game between East and West. While this scenario would damage BIG tradition, it would preserve the significant and historic rivalries of the old BIG, while creating some interesting new rivalries, especially in the East.
West
Kansas
Missouri/Notre Dame
Nebraska
Iowa
Minnesota
Wisconsin
Illinois
Northwestern
Purdue
Indiana
East
Maryland
Rutgers
Virginia
North Carolina
Georgia Tech
Florida St.
Michigan
Michigan St.
Ohio St.
Penn St.
From a geographic standpoint it would be perfect and travel costs would be minimal, especially for the Western division.
