I know almost only counts in horseshoes and hand grenades but Tyson "almost" pulled the greatest come from behind win, possibly of all time, but Douglas was saved by the bell. Besides, when has coming off the floor to win a fight been determined as a must for claiming greatness? Would Tyson have passed your "greatness" test if he was dropped against Tucker in the first? He would've come back and won a UD, right? So what's more impressive: absorbing the bomb and staying on his feet or getting dropped but coming back to win the fight? What if Bruno dropped him? Or Smith?
