But if the big12 expands now and they don't get in then they'll probably never get in. Better to have nothing happen now than that regardless of financial disparity. Take Memphis for instance, fed ex looks more than willing to fund them, they'd be fine in that situation and maybe have time to raise their profile. UConn already has a bigger budget than some P5's, like Utah for one.
Better to take their chances in that situation than know they're out forever.
