That would be similar to Jackson moving up and knocking out Holyfield with a body shot.
Just playing devils advocate here ( because not even his family would accuse James Toney of being a natural Middleweight ) but isn't that exactly what James did, go from a Middleweight title, to KO'ing Holy with a body shot at Heavy?
