Super Middleweights : James Toney vs. Michael Nunn
Re: Super Middleweights : James Toney vs. Michael Nunn
Not sure it would be any different result if it was at the same time as the middleweight fight only the higher weight. If it was after their middleweight fight, Nunn didn't get any better after that fight and Toney did. So I would go Toney UD
