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

[Taeth]

Like Pacquiao moving up to face Oscar De La Hoya, and RIcky Hatton?
Like Adamek against Cruiserweights?
Like Hopkins against Tarver?
Or Calzaghe against Hopkins?
Wright against Hopkins?

People have always fluctuated in weight.

The reason I am not missing the point is that Mayweather's style is condusive with being the bigger guy, the reason he has always done well against larger opponents is because speed is his biggest ally. The guys who will be able to connet most against Mayweather are the fast guys, the guys who will be able to force Mayweather to fight overly defensive are fast guys. Him being the bigger man does him little favor against JMM. The most weight MAyweather ever put on at WW was 3 pounds for the Baldomir fight, he weighed 1 more pound than Pacquiao has of late, and nobody would ever toute the size advantage for Pacquiao against JMM despite him now having more experience at higher weights, JMM seemed to do fine against Manny, and when they fought Manny came into the ring at 145 which is 3 pounds less than he did against Hatton and Oscar De La Hoya, and 1 pound less than Mayweather was against Zab Judah. That's right, Manny weighed 1 pound less in a 130 pound fight then Mayweather did in a welterweight fight. Furthermore, Corrales was 3 pounds heavier than Mayweather weighed in at against Judah when Mayweather fought him at 130, as was Castillo when he faced Mayweather. What I am saying is that Mayweather may have grown, but he was a small lightweight and 140 pounder fighter, and there are lightweights who are bigger as lightweights or as big as Mayweather is as a welterweight. Mayweather fights at welterweight, but he doesn't cut weight to do so, he comes in naturally, and he weighs-in hydrated.

I have no problem with fighters going up in weight, it usually a good thing. But Thats not what im saying. But JMM fighting 145 pound Pacquiao is not the same as him fighting a welterweight like Shane, Cotto, PBF, even though they all fought at much lower weights earlier in their careers. Timing is everything. The timing for a Welterweight showdown between Floyd and JMM is wrong. I dont think Marquez should ever fight at that weight. So basically what you are saying is that JMM and Floyd are on even terms when it comes to the weight. That seems to be your argument, but I think you took being a Mayweather fan out of the equation, you would realise that is not the case. This isnt about defending Mayweather, its bout the direction boxing is headed.

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.

JMM weighed 140 on fight night of the Juan Diaz fight... I'm guessing JMM will weigh-in at 138 then weigh 140 on fight night with Floyd... Floyd possibly weigh-in at the limit at 144/145 (?) then weigh 148 to 150 on fight night... JMM giving away 8 to 10 lbs to Floyd on fight night will be very dangerous when it's coupled with the many other physical advantages Floyd enjoyed over JMM...

Size - 8 to 10 lbs. advantage to PBF
Speed - PBF is much faster
Reach - 5" advantage to PBF
Age - JMM is older by 4 years
Height - 1" advantage to PBF

Mayweather hasn't put on 6 pounds for a fight since he was at 130, I can't see him doing it, he makes 143 too easily, and he trains all the way up to the fight. He's faster physically, but Mayweather has been fighting slower guys, and obviously Marquez can deal with speed. When Mayweather fought at lightweight he also weighed 140 coming into the ring, Marquez could easily put on more muscle and still be fine speedwise, I can't see him weighing only 140, and even if he did, it only helps him to be lighter against Mayweather.

I too think about this constantly, but no of us will know until fight night.
As a fan, I would love nothing more than for JMM to pull the upset.
