Who's the best current Welterweight?

[CutMeMick]

If Mayweather considers himself a Welterweight, than it's him. If not it's Mosley. Cotto a close second.

VD what has SSM done at 147 that makes him the best there?

I think Cottos #1, Baldomir #2, Margarito #3, SSM #4.

Being that PBF last fought at Light Middle thats where you would have to rate him, IMO.

It's the fact that I would pick Mosley to win over all 3.

I see your point.
What about rating them as far as what they've done. Not who beats who cause I would agree with you I think SSM beats them.
