I think the Big 12's best move at this point is just to bide it's time for the inevitable collapse/breakdown of the ACC and just see who we can scoop up from that fallout. Would much rather have some combination of VT, Louisville, Wake, UVA, NC State, NC, Duke, Miami, GT, SMU, Stanford, Syracuse, etc. (assuming Clemson and FSU go SEC or B1G, but I would gladly take either of them), than jumping the gun and adding Memphis or Boise State or UConn.
We have built a position of strength relative to where we could have ended up and are in a somewhat stable position. Time to ride that out until chaos takes over once again and be poised to take advantage.
