The Ghosts vs Cobra, the two young town warriors. I got the Ghost by mid-round TKO. Pavlik has the height and reach advantage plus power in both hands. I also think Pavlik's boxing skills were underrated. Cobra wasn't known as a power puncher, and Pavlik's chin is game. I also think Pavlik has a better overall resume.
Pavlik would win, but unlike some I rank peak Pavlik very highly at middle weight. At his peak he is a all time hth fighter imo.
I think Kelly would win in a spirited fight. I don't know if he would stop Dewitt. Not the Dewitt who fought Hearns... The later Dewitt he might stop, yet the later Dewitt had more experience and used the ring better.
