Who would've been a tougher fight for Mayweather: Antonio Margarito or Paul Williams

[Chuckguy]

Paul Williams imo

I with you Larry but I sill think floydie beats them both

[CJRock]

Given a level playing field , anywhere but Vegas, both Margarito & Williams would have beaten Mayweather. It took Mayweather , The NSAC, USADA & Vegas boxing officials conspiring together to keep Mayweather's 0 intact
Mayweather almost certainly cheated his whole career & was allowed to do so

Williams. Margarito was too slow.
