The Ghost vs The Cobra.
Pavlik lost to Hopkins and then to Martinez,at the tail end of his boxing career. Pavlik was at his best when he fought and defeated Jermain Taylor(Twice),so let's go with That Version of Pavlik.
As for DeWitt,he was more or less a Hot or Cold type. I thought he looked his best in a Losing effort against Hearns in 1986. He gave a Good Account of himself by going the distance with The Hitman,and not even hitting the deck once nor getting seriously Rocked either. So,Let's go with That Version of DeWitt.
