I dont know about that. Botha fought everyone in the pros. He did ok against the better fighters and beat a lot of decent guys. Sanders on the other hand doesnt have much to his resume besides the Klitschko win, which he would have never duplicated had they rematched.
Sanders beat Botha three times in the amateurs. He would have beaten him as a professional as well. Strange the two never meet. It would have been a good regional fight at the very least.
Johnny du Plooy, now there was tough Transvaaler! He woulda wiped the floor wid bof of em in his prime!
