Martinez, Pacquiao had his chance and he blew it when he lost to Marquez then got beat by bottlejob disgrace Bradley. 154 would work.
Did Floyd put 15 pound of muscle back on yet? He has to put 15 pound of muscle back on and then he might fight if he no ask for 65/35. Manny make nice offer 55/45.
Martinez has everything that Pac has and is a bigger guy - that would be a stiff test to Mayweather's ability and resilience.
As a selfish fan, Martinez as it's a tougher fight for Floyd. I'd like to see Sergio fight someone at 154 before Floyd to remove the "drained" excuse that would forever accompany the win for Floyd, if he were to win that is. May-Pac would be fun as a spectacle and bring a lot of attention to the sport though, which would be awesome.
