Since I haven't posted here in a while, here's a future realignment scenario!

Things start going down around 2033, as we approach the expiration of the ACC GOR. The Big Ten goes all in and extends invites to UVA, UNC, Duke, GT, Miami, and ND. The SEC responds by adding VT, NCSU, Clemson, and FSU, bringing the top 2 leagues up to 20 members.

Numbering just 5, the ACC left-behinds shack up with the Big 12. Memphis, USF, and Temple are raptured away from the AAC, and the Big 12 rebrands as the Big 20.

The MWC picks up a disgruntled SMU from the AAC along with Rice and Wichita State. The MAC takes the opportunity to add WKU and MTSU from CUSA. Navy flees the depleted AAC to return to FBS independence.

The AAC, down to just 8 members again, adds FIU for a 2nd Florida school and follows the CUSA 4.0 strategy of standing pat at 9 members. CUSA elevates EKU, UTC, and SFA from the FCS. The Sun Belt and Pac-12 remain unchanged.

Thus by 2037ish we have a P4 with 2 clear leaders, and a G5 with 2 clear losers.
