I really want to see him fight Cotto again. If Arum can negotiate Margarito through his ban and give him a tuneup to make him look a credible opponent again then a Cotto rematch would be huge. It would bring huge publicity to boxing for all the wrong reasons but it'd make a ton of money, something Arum won't have overlooked. There's a hell of a story to sell, a big hook to bring the punters in and get them ordering the PPV. No matter what Margarito, Cotto or Arum say publicly over the next year about whether it could happen I'm sure it will barring something going wrong, there's just too much potential money to be hoovered up for it not to happen. I think Cotto wins too.
