UCF draws fans and has $$$. That beats a good portion of the current ACC (BC, Cuse, UVA, Pitt, Duke) all come to mind. Plus, if you want to make the ACC more regional like the sec, UCF is a good option. The program is continually growing.
Heck, if USF could ever get their act together, they would be another option. The option to really keep an eye on is Memphis. Like SMU, there is a huge investment into the program going on right now. Give USF, Memphis a share of P4 options and $$$, and they could elevate.
