Big Ten wants AAU schools.
The list of P5 non B1G/SEC AAU schools: Duke, Georgia Tech, Stanford, Arizona, Cal, Colorado, Kansas, UNC, Oregon, Pitt, Utah, Virginia, Washington
The Big Ten also wants big fans bases and media markets so they’ll make exceptions for: Notre Dame, Boston College, Miami, Syracuse, Arizona St
I’d also not 100% rule out them going after Oklahoma/Mizzou in an attempt at getting the best of the Big 8 gang back together as a bridge to their new Western flank (OU, CU, NU, KU, MU).
Most likely scenario, whatever it take for ND, fortify western flank with UO/UW and possibly more, and maybe make a play for UNC/UVA.
The SEC wants geographically close schools with large fan bases in the Central or Eastern time zone that are good at football and/or bring at good contingent of “other” to the table (academic, markets, basketball).
List of non SEC/B1G that fit in order of most wins: Notre Dame, Florida St, Miami, Clemson, Virginia Tech, West Virginia, Georgia Tech, Pitt, UNC, Texas Tech, TCU, Oklahoma St, Louisville, Virginia, NC State, Baylor, Duke, Kansas, Iowa St, Wake Forest (after UNC most are extreme long shots, save UVA, Duke, Kansas)
Most likely scenario: FSU/Clemson are virtual locks, then the SEC makes a play for UNC/UVA by offering to take their partners Duke/VT…successful or not then who knows..?..lock out Big Ten from moving South by locking down Miami/GT, grab more territory with West Virginia/Pitt, or try to make Oklahoma/Mizzou feel more at home by bringing in Oklahoma State/Kansas (Bedlam/Border War), settle for NCSU/VT if they can’t pull in UNC/UVA, lots of options.
So both lists have 20 schools and some overlap, these 8 are they only ones they may be fighting over:
ND (obvious top piece on the board, likely Big Ten or bust/stay independent for them)
UNC, UVA, Duke (both would take these, likely the biggest remaining flashpoint in realignment outside of whether of not ND joins the B1G)
GT, Miami (next tier may be more or less desired depending on how much expansion is going on)
Pitt, Kansas (filler that both would accept to round out numbers)
