I remember when Cotto fought Sosa, George Foreman was so impressed he made the comment "If I was a betting man I would NOT bet against Cotto" and he meant it, you could tell. I thought of this before the Mosely fight but still went with Mosely. If he fights Paul, I'm taking George's advice... its a tough matchup but I think Cotto has what it takes to pull out the W.
This is a tough one. Williams is a matchup nightmare with anybody in the division and with his amazing amount of punches he throws he uses that like a defense. In my times watching Cotto i've now learned to not underestimate him and I think he would find some way to get to Williams, possibly with body shots and win a close UD.
Paul Williams Easy, you need one punch knockout power to beat Williams if you're a shorter welterweight. Cotto's power creates accumulative damage but it's not one shot and your out of there like Roy or Tyson. Paul Williams will reign til someone knocks him the fuck out....best chance belongs to Cintron(and I don't think he's that good, Just that strong.)
Paul is a freak of nature but I see Cotto getting the victory. He can punch he can box and he can fight smart. I think he could get the job done...................I think.
