He wouldn't kill Roy... give me a break when was the last time Bernard stopped a real middleweight or larger? Tito wasn't, Oscar wasn't. I love Bernard, but don't get carried away, Bernard only was the aggressor in the last few rounds, the rest of the time it was Pavlik's forward movement that allowed Bernard to get largely as many punches off as he did, and Pavlik is way easier to hit than Roy.
Neither of them are what they once were, but Hopkins' style works better against the younger guys. He doesn't have that same tiger he had in his prime, which is why he isn't as good as in his prime. I still say it could be a close fight.
