Styles make fights. Hearns would stop Pavlik, even though Barkley beat Hearns. But I think Pavlik stops Barkley.
Barkley could also stop pATVlik. He was badly hurt vs taylor who aint a great puncher and was a terrible finisher
Pavlik should win a close one but I could see Barkley dragging him into the kind of brawl where he was in his element. Pavlik wins a narrow majority.
