Sanders was TKO by Rahman not Ko'd. He gassed out while he was ahead on points. Moore wasn't bad by any means. Either Klitschko was destroy him. Moore was ko'd more then Sanders also not to mention he stopped Cooper in 3 rounds.
Moorer was a giant slayer! He nearly killed the 6'10, 275 lb Mike White! Vitali wouldn't stand a chance.
If you look at the pre fight introduction...The top of Moorer's head only reach's white's chest! White looked scary eying him down.
Not mention Moore fought a life and death fight with Bert Cooper who Sanders made quit which is on youtube.
