muhammad ali, because he really is the greatest. gatti and ward, because they gave us some of the best ever. hitman hearns, if you look past his losses, he is one of the most dangerous guys to ever step in the ring. he always gives 100%, and always beat the **** out of his opponents. i am surprise none of the martial artist said this, but right now my favorite is barnard hopkins. not just because he is a fellow east coast brother, but he approaches bxing like a fighting art. he is mean, and he looks to hurt his opponent as well as win the match. if the knockout doesnt come easy, he pound the life off your body, and makes sure you dont want to get in the ring with him again. he is laughed at because he wont fight for less than 50%, but then, why should he take less just because somebody doesnt want to? he does a good job intimidating his opponents, including the interviewers. roy jones, of course he is the most skillful fighter to watch, has lots of confidence, except i have a feeling he is avoiding hopkins. floyd mayweather, even though he lost to castillo, he is the best package and the most adaptable fighter to his opponents.
