If Pac and Mayweather dont want nothing to do with him, I think from what we've seen tonight that Mosley could beat Williams
He doesn't have the same thing that Martinez had...counter punching style and a southpaw stance. That's what made both Martinez and Quintana so successful. Mosley COULD win...but his chin would DEFINITELY be tested. If he punches to the body and follows up top the same way that Martinez did, he can most likely KO Williams.
Angulo would KO Mosley...Angulo has the power that Margarito DOESNT have. If you watch the fight again, Mosley got tagged many times on his way in by some solid shots. Angulo has good power to put Mosley on ***** street. I think it would be an amazing fight while it lasts...but one that I see Angulo making a highlight victory out of.
Mosley would have a tough time with Williams if Williams stayed on the outside. Remember Mosley is orthodox.
