There is a lot of jumping around, but that is because in the grand pursuit of the almighty dollar, there now exists a maze of championship belts and weight divisions that in some instances are only separated by 5-10 pounds. For instance, a top lightweight fighter can start at welterweight 140, move up to superwelterweight, and then advance to junior middleweight, and not even have put on more than 25 pounds in weight. The middleweight division is 168. Someone also erroneously pointed out that Roy Jones started out as a welterweight and moved to heavyweight. No one has ever done that. Not even Roy Jones. Roy Jones was only the 2nd boxer in history to be the middleweight as well as heavyweight champion. James Toney also accomplished this feat for about 3 days, before his victory over John Ruiz was overturned due to a failed drug test. The fact that they both beat the stiff John Ruiz to win something called the WBA heavyweight championship somewhat dilutes the potency of the accomplishment in my eyes. I think the first guy to win the middleweight and heavyweight championships was Fitzsimmons, and he did it at a time where there was one middleweight champion and one heavyweight champion, not an IBF, WBC, WBA WBO, IBO, NABF etc. One of us could probably mail order a title at this point. The other thing is fighter's styles make for good fights. If you put a Gatti and a Ward in the ring, it will be a "good fight" because neither guy has any defense to speak of and they don't move laterally. They come forward into whatever you're throwing. But put them in the ring with a speedster like Mayweather and they'll look sluggish. Alot of it also has to do with the referee, who is, ahem, hand-picked by the head of the alphabet soup boxing organization who is sanctioning the fight (i.e. the head of the WBC, Jose Sulaiman, is Don King's whipping boy, hence, Don King's fighters are generally the ranked contenders for the WBC belt; this is why you never see two great fighters with different belts fight each other unless everyone agrees on the split - - see Tarver v. Johnson, both men had to give up their respective belts because they had to fight the No.1 mandatory contender/challengers - - of course, it makes no sense that if Tarver has the WBC version and Johnson has the IBF belt, how is Tarver not the No.1 contender for Johnson's belt??? but anyway . . .) Back to the referees . . . a good example are the legendary Sugar Ray Leonard/Roberto Duran. Duran was the straight ahead basher/brawler, Leonard the quick, speedy counter puncher. In the first fight, the ref allowed Duran to clinch and hold, to fight his fight, be physical, and so he pretty much whipped Leonard. In the second fight, the new ref didn't allow Duran to clinch, which opened up the ring for Leonard and let him dance and do all that stuff he liked to do. Anyway, don't know what point I was trying to make originally, but I have to agree that welterweight and other lightweight divisions are definitely where its at for great boxing. And Zab Judah might be better than Mayweather, very similar style to Mayweather, he currently has ALL of the belts at some weight around there.
