Paul William vs Carlos Quintana 1 and 2, if we were to analayze a potential matchup between SSM and PW?
They are not really similar styles. Because Quintana moves around on his feet alot more while Mosley likes to trade. But what you should know is that Williams can be hit. And Mosley would probably be the best combination puncher Williams met. Add that with Mosley's power hand speed and accuracy and you have a very winnable fight for Mosley.
That if Shane can keep out of PW's range and have him leaning in to throw punches and then close the gap to counter he will land on PW often, but if he lapses for even 1 moment then he could get seriously hurt.
