FWIW, I predicted on another board how the superconferences might lay out but this was before the most recent moves like Maryland to the Big 10:
The SEC:
Alabama*
Auburn*
Arkansas*
Florida
Georgia
Kentucky
LSU*
Mississippi*
Mississippi St.*
Missouri*
North Carolina
South Carolina
Tennessee
Texas A&M*
Vanderbilt
Virginia Tech
* - West Division
The Big 10:
Boston College
Illinois
Indiana
Iowa
Nebraska
Northwestern
Notre Dame
Michigan
Michigan St.
Minnesota
Ohio St.
Penn St.
Purdue
Rutgers
Syracuse
Wisconsin
The Big XII:
Baylor
Clemson*
Florida St.*
Georgia Tech*
Iowa St.*
Kansas
Kansas St.
Miami*
Oklahoma
Oklahoma St.
Pitt*
TCU
Texas
Texas Tech
Virginia*
West Virginia*
*- East Division
And the Pac-14:
Air Force
Arizona
Arizona St.
California*
Colorado
Oregon*
Oregon St.*
San Diego St.
Stanford*
UCLA
USC
Utah*
Washington*
Washington St.*
* - North Division
Now, with Maryland in the Big 10, I can see Virginia joining them with Boston College and Syracuse out unless Notre Dame refuses to join.
ND is playing for a national championship this year. They are once more relevant. They won’t join a conference. A few more 5or 6 win seasons and they may have thrown in the towel but not now and not soon.
