Let's say you get to this point and you want to go to 16:

ACC North: BC, Syracuse, PSU, MD, West Va, ND, Miami
ACC South: GT, CU, WF, NCSU, UNC, Duke, UVa

This ACC is not going to look toward Texas for any reason - if they want 16 they are likely to go for SC and Navy allowing Navy whatever accommodation they need.

B10 East: Rutgers, Pitt, Ohio State, Indiana, Purude, Michigan, MSU
B10 West: NW, Wisky, Minn, Iowa, Nebraska, Mizzou, Illinois

This Big 10 is not looking east unless MD is again planing a defection. I think they go for Kansas and Oklahoma.

SEC East: VT, UK, TN, UGa, Fla, FSU, Auburn
SEC West: TAMU, LSU, Ole Miss, MSU, Bama, Arkansas

Only Texas does anything for this SEC. Whither Texas (and pal TT).
