I ticked Dawn here, but it's for lack of any clearer options. No other rivalry will be the same because no other coach, even if they were to beat UConn multiple times, has that combination of bitterness and classlessness that Muffet has.
Dawn catches some deserved flak for some of her nonsense, but fundamentally I like her and I respect her as much as anyone else in the game. Plus she and Geno have been coaching together in USA Basketball for what seems like forever now.
Compare that to Muffet, whom USA Basketball, much to its credit, wouldn't touch with a 10 foot pole.
