I rate campillo higher than cleverely, and thought campillo would give kovalev a decent fight well he went in there and just crushed him. Not sure what clev got to offer kovalev, kovalev has a sick punch, good workrate for someone who has a punch like that and from what I've seen a good chin, kovalev inside the distance like 8ish. Granted I've only seen kovalev 4 times but he's really impressed me.
