Martinez is way too much of a risk.
Mayweather won't go up to 154 to face him. Forget about 160. Martinez would have a HUGE size advantage and would be much stronger. He would likely out-box Mayweather to earn a decision.
If the Pacquiao fight doesn't happen, expect Mayweather to go after Berto.
Heard the same when the Mosley fight was in the talks.
Honestly i think its moreviable the Martinez fight than the Berto one, Al Haymon wont ruin his young rising star just now.
I don't expect it, but I could definitely see it if Mayweather were to beat the hell out of Pacquiao. He wouldn't have a challenge at 147, due to circumstances I doubt he would ever end up in the ring with Paul Williams, and Sergio fights Floyd's kind of fight so Floyd would have a decent chance.
I think it might happen, Martinez thinks very highly of Floyd and would like to oppurtunity to fight them, I dont think it's a good move for FMJ to go back up to 154 yet alone 160. That's too big for him, But it would be an interesting fight at 154.
I still want to see him fight in the U.K
