He is not over rated at all!
If he is then so is Tyson and Ali! If anything Ali is over rated for beating about 5 names through his career including Henry cooper which isn't anything to brag about tbh.
At least Roy beat a prime bernard and prime toney and hold all the belts etc etc and then win a world title?
Some people might say "yeah but John Ruiz" but that's like saying manny vs wladimir klitschko!
