That would be a stinker. Byrd has the better movement and jab imo and would outbox the lazy and a bit stationary Toney to a close UD in a very very boring fight.
Difficult to say, and largely dependent upon how these two choose to show up. Toney has certainly proven that he can at least contend with heavyweights, while Byrd was one of the division's best players for close to a decade. I suppose if they were to fight this minute, I would have to go with Toney. James is at least still competitive, whereas Byrd is rarely making an appearance anymore, and when he does, he's usually losing. In 2008, Toney by a decision or late stoppage..
