Nunn. Pavlik has power and a nice bit of talent. Nunn had a lot of talent, and he was smart enough not to bust his nut if he had someone in trouble.
I tend to agree, that Mike would school the shit outta Pavlik. Hell he might even stop him. Nunn had more power than Taylor.
I could see Nunn running his way to a stinky decision win, but I could also see Pavlik grinding Nunn down to a late TKO or possibly pulling out a decision. Nunn looked impressive in some of his prime, but he didn't look all that impressive against Barkley and Pavlik would come at him the same way, but with faster hands, better accuracy and more power. I think we need to see more of Pavlik (especially against a tricky boxer or two) before making an accurate comparision.
