You could see after the B-hop fight he was totally heart broken.... Especially when Hopkins gave him his post fight(read massacre) pep talk... There's something to say of good sportsmanship,,,, but when you've broken down a man's mind, body and spirit through the sport he's dedicated his life too, going up and saying the likes of 'don't worry, you're still good, just because I totally wasted you doesn't mean you still can't beat C grade fighters', it's just wrong...
Leave the guy to his broken spirit...

And that's not to say I think Pavlik can only beat C grade fighters, but that pep talk from Hopkins post fight probably got him closer to a Pavlik uppercut to the nuts than anything he did during the fight.
