But travel costs have to be much higher for an Eastern team. That likely offsets any financial gain. There also remains the stability issue of the Big 12. I don't think they're that unstable, but should Texas leave, it will really hurt. And that is possible, although unlikely in the near future. Combined, the ACC seems like a much better fit if Rutgers is choosing.
Honestly, I don't see Rutgers and the Big 12 being that big of a risk. While I would think Rutgers would take any BCS AQ conference over the Big East (as West Virginia did), I'm not sure the feeling is mutual. The Big 12 may not go to 12 anytime soon, and they certainly are not going over 12. Louisville seems like the obvious first choice, with Rutgers seemingly down the list for #2. And let's face it, if Rutgers brought any sizable TV market presence, they would have been scooped up by someone else long ago.
I don't see how any of this forces the ACC. If Rutgers goes, they still could explore a UConn/ND expansion. Not sure anything happens w/o Notre Dame anyway. I don't see how UConn/Rutgers brings enough to the table to push the ACC to move forward. And it's always financially better to wait for Notre Dame if there's a remote possibility they may join the conference.
