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

[XaduBoxer]

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.
