Pavlik is the more powerful man with the harder punch, superior physical strength, and a better jaw, longer reach, better jab, it's a no brainer Pavlik KO in 5 or 6 rounds..:yep
Trinidad actually handled middleweight pretty well. He did beat William Joppy for the WBA middleweight title, and Hopkins had to be in his A+ game just to neutralize him, and even then he still kept coming forward. If it was Tito in his prime, I would give Trinidad a 50% chance to win. Right now? I would say Pavlik would massacre Trinidad.
