Ohio State - USC comes to mind.
tOSU/USC is at the top of my list as well.
Georgia/Florida may be interesting when it rolls around.
Others are: Kansas/South Florida, Auburn/West Virginia, Kansas/Oklahoma, Meechigan/tOSU (can't get away from that one living in Ohio), and of course all the LSU SEC games (and App. St./LSU - worried a little about that one).
