Casamayor definitely could frustrate Diaz, outbox him, frustrate him with fouls but I think the time is right for Diaz in this fight. If he's ever gonna beat a guy like Casamayor it would be this Casamayor, an older one who's not in his prime. A guy who's constantly on top of you, constantly throwing punches can be a difficult fight for a guy that's not really in his prime anymore.
