Who should Antonio Margarito fight next?

Now that Antonio Margarito sits on top of the welterweight division, who should Antonio Margarito fight next? I. We want opinions - there are no right or wrong answers. Just let us know : 1. Who you want to see Margarito fight next. 2. Why you think that opponent would make a good fight. 3. Your hypothetical prediction. II. Let's kick off the discussion : Here's my take! I'd love to see Antonio Margarito fight Paul Williams again next. Both Margarito and Williams have tremendous work rates, chins and stamina. Within that context, Margarito is a brawler while Williams is a technician. Also, both have something to prove : Margarito that he just lost because he started slow; Williams that his first win over Margarito wasn't a fluke. This is a fight that would carry lots of action, and a good story. To put the cherry on top, Margarito-Williams II would be a welterweight title unifications fight to determine the top fighter in the division. I'm picking Antonio Margarito for the fact that his destruction of his last three opponents since fighting Williams - Golden Johnson, Kermit Cintron and Miguel Cotto - show that he's for real in learning the lessons of his Williams loss. Also, Paul Williams carries an explosive left, but it comes far and few between his smaller punches, and against Margarito, you need to hit him constantly with power to have a chance. Williams is a good technician, but he's no Money Mayweather - and if you aren't going to don't have that Mayweather footwork, then Margarito will eventually catch you. If Antonio Margarito and Paul Williams were to have a rematch, I'd pick Margarito via unanimous decision.
