I think this will be a perfect matchup, but will never be made anytime soon. Anyway who will to take if they fought now?
I think I'd go with Julio honestly. He's got better hand-speed and better combination punching, and his defense is better. Plus, he's faced waaaaay better competition. I'm not sure if he knocks Chavez out, because Chavez hasn't been in with anyone his size, let alone someone who can punch. But either way, I'd go with Julio. Probably the reason this fight won't happen - at least not anytime soon.
