I wont fancy any bets on this. Could see Rubio being a step up but I'm not sure if Rubio beating Lemeiux maybe resulted in some slightly over estimating him. It's hard to call this but I am going with JCCJR by a very very narrow decision similar to the Zbik fight.
rubio will hang tough and give chavez some rough spots but I think the fact that roach has chavez boxing more will make it easier win for chavez than it would be otherwise.
