Who should be next? Cotto, Williams or Margarito?

I seriuosly doubt any of these fighter would lead in with their faces and shoulders. If I had to pick, I'd say Williams has the style,punch and stamina to beat Mayweather, though the other two are great opponents as well. It's too bad only Cotto has an ECONOMIC chance of facing Mayweather. I miss the Maweather at jr. lightweight--he fought them ALL. Man, I wish Pernell Whitaker were around ...
