Jumping up 10+ lbs In Weight At 35+ Years Old

[Taeth]

When has boxing not been like this? When Armstrong won 3 titles in three different weight classes? When Jack Dempsey fought Willard? When Ezzard Charles became heavyweight champion? What about Joe Walcott moving up? Or Sam Langford? Or Greb? Or Tunney? Or Archie Moore? Or Bob Foster? Or Holyfield? Leonard? Ray Robinson? THomas Hearns? Roy JOnes Jr? Roberto Duran? ARguello? The list goes on and on of guys who have consistently moved up in weight. Marquez hasn't gotten weaker, when have we ever seen him throw more punches than against Juan Diaz? He sure didn't look old or slow against Pacquiao or Casamayor.

Also ONCE again you are ignoring the fact that Mayweather isn't a natural welterweight. We see Paul Williams, Miguel Cotto, MOsley, Margarito, Baldomir, Clottey all weigh up to 160 coming into the ring while Mayweather doesn't crack 150 as a welterweight, Thats the difference, he is 10 pounds lighter than these guys, and far closer to JMM and Manny Pacquiao in weight. So where is your logic? JMM won't try to put on too much weight, but MAyweather won't be 10 pounds heavier than him, they will likely be within 5 pounds of eachother, thats not considered being ina different weightclass. Their power will be similar, their speed will be a lot more comparable than it would be if Mayweather was still fighting at 140 or less because he would have retained a lot more footspeed. Their strength is unimportant because MAyweather isn't a guy who imposes himself.

Besides isn't the fight at 143 at not at the actual 147 limit? Mayweather is never known to put on more than 6 pounds and that was way back at 130, he's only put on half that during his campaign at 140 or higher when comparing his weight before a fight to afterwards.
