I don't really see it. I cannot find an angle wherein JMM can give it a GO with any advantage.

Exploit the ring rust by maximizing the length of action on each round maybe... and to hopefully be there with enough firepower to finish off Floyd, if the latter would ever allow for a chink in his armour to surface.

It is almost that, all avenues lead to a PBF Jr. win, moreso now with the extra poundage, ensuring size supriority.

If this is a chess match, only a blunder from Lil' Floyd, combined with an opportunistic and an overachieving performance from Juan Manuel Marquez, can deny Floyd Mayweather Jr. from getting the victory.
