in my mind the only possible winner is bradley over witter in the other cases (except prescott-khan), the "upset" was by a fighter with a proven pedigree or in many cases a former world champion... i mean seriously how much of it is an upset for bernard hopkins or manny pacquiao to win a fight? thats what they do but tim bradley seriously NO ONE knew who he was... he wasn't even a "contender" level type fighter... and he came out of nowhere and beat what many people were saying was the best 140 lber out there... made him look terrible the prescott-khan one, well all that showed was that khan wasnt that good, i dont think it was a huge upset
