imo i don't see mayweather fighting a junior middle for long. he has no power at that weight. who's he knocking out at 154? (besides cory spinks where both fighters would be decided who's going to be 'it' in a game of tag)

1) winky would be too big for him now that he's settled in at middleweight.
2) there's no big name fighters aside from de la hoya at junior middle

tons of fights at welter.
