If FSU leaves, I think the 2 league super football league will be created.
Big Ten
East - PSU, MD, UNC, BC, Virginia, UNC, Clemson, Duke, GA Tech, Notre Dame
Midwest - OSU, MSU, UM, Indiana, Purdue, Illinois, Northwestern, Minny, Wisconsin, Iowa
West - Nebraska, Kansas, Colorado, Oregon, Washington, Stanford, UCLA, USC, California, Utah
SEC
Southeast - Florida, FSU, Miami, S. Carolina, Georgia, Bama, Auburn, Vanderbilt, NC State, VA Tech
North - Louisville, Syracuse, W. Virginia, Pitt, Kentucky, Oklahoma, Missouri, Kansas St., Arkansas, Tennessee
West - Arizona, ASU, Houston, Texas A&M, Oregon St., Washington St., LSU, Miss, Miss St., Texas
Maybe the SEC breaks up the Florida teams to balance out the divisions (maybe FSU and Miami in North with Tennessee and Pitt in Eadt or something like that). There are also a few different conference variations for some teams a few options for the last couple of spots, but I think that is a rough outline for a 60 team super league. Each team essentially plays 9 division games, 2 non division games, and then a 16 team playoff to decide the champ.
