Let me make it clear that I do not condone dirty fighters. That said, there are some fighters, who for some reason or another, get away with the some of the most illegal and dangerous tactics ever seen in a boxing ring. I'll only name one here because I'm interested in the opinions and picks of the board. Though I've always admired Evander Holyfield, his head butting tactics were something I had mixed feelings about. Nevertheless, it was a very clever, if not a disturbingly dangerous move. Holyfield would go in as though he was about to throw a straight left. This punch was nothing but a decoy. He would follow through with the left by ramming his head into his opponent. It was actually a one -two punch with the left setting up the butt. This has never been officially discussed by any magazine, boxing commission or blow by blow announcer. (Accusations made by the Tyson camp were dismissed. Mike was dirty too but not smart enough to get away with it.) Yet, it was the deciding factor in his fight with Hasim Rahman. Are there any other fighters that come to mind who, though they were super talented, had brains like steel traps?
