I think possibly the RJJ who beat ruiz would beat every heavyweight out there today except maybe vitali?

RJJ did beat a terrible heavyweight champ in ruiz- one of the worst of all time but then so did haye in his titlefight vs valuev.

The only reason RJJ dropped backdown in weight after winning title was cos there was no way he would of stepped in the ring with lennox lewis so it was pointless him staying at that weight.
