Probably my least favorite fighter in history. John Ruiz. I'd take Andy Ruiz to win, certainly won't be by a knockout with John Ruiz thick skull.
Andy’s fast hands are likely to be the key here, if he could get off quickly and often he would outbox Ruiz to a win. If he stands back and lets John hit and hold it could be a long night for fat Andy. I’d go for with Andy Ruiz by Decision.
