Chisora and Haye make boxing look classless and ungainly while there is an understanding they're jokes.
It pains to to watch and listen to Mayweather. Yes he's a good fighter but he's benefitted from the press than boxers like Hatton and Oscar De La Hoya brought in. By the time they got older, Mayweather bet them and the devision got so much press that every fighter got a high profile. He's dodged Manny Pacquiao untill both are out of their primes. Had other boxers like Joe Frazier dodged Muhammad Ali and George Foreman, he'd have been undefeated and considered pretty good, but undefeated means nothing if you avoid the best boxers anyway.
The claim that he's also successful in 5 weight divisions I think's a bit misleading. From when he started boxing as a 19 year old to his now 35 year old self, he has gained roughly 24lbs (10.9kgs). The difference between Super Featherweight and Light Middleweight is from 59kgs-69.9kgs. Robert Duran made a 15kg jump in weight devisions while Manny Pacquiao has gone up just short of 20kgs since being a flyweight.
His attitude of ''I make the most money, I spend lots of money, I'm better than you'' doesn't endare me as a fan to watch any of his fights either. I'd rather not spend $40 for a PPV to support a guy who thinks he's better than the people paying to watch him fight. Most obnoxious boxer of all time.
