Who would win, i know it sounds odd but is size everything?...
I see Roy wininning an easy slide of a decision for the whole fight, Toney may be tougher and stronger at heavyweight than he was a supermiddleweight but he sure as hell would be alot slower too.
And if he couldn't touch Roy st supermiddle weight, there is no way in hell that the same Toney who fought Rahman would beat Jones at supermiddle weight.
