Definitely, I think the majority of people see Mayweather's prime being at 130lbs. But you never know, he has a big bout against Mosley coming up, and possibly Pacquiao after that, Mayweather could, and may have to top his best performances in the upcoming bouts.
This question and poll for that matter is utter bull**** and ridiculous to say the least. Money May isn't even in his prime anymore and would still beat any version of Mosley in horrific fashion. It would be a brutal and completely embarrassing ass whooping in which Mosley would get beaten from pillar to post. It would resemble the Money/Corrales fight all over again.
