The Jones who beat Ruiz fights the Holmes of 1986 that lost an extremely controversial decision to Michael Spinks. Who wins?
Holmes knocks him out RJJ got caught with a few solid right hands from Ruiz and Holmes was able to badly hurt Spinks a few times with right hands. If Holmes can still land on Spinks he can land on RJJ who was also smaller than Spinks by quite a considerable margin in height and weight.
I love RJJ but its very hard to see him being able to stay away from Holmes. RJJ of the Ruiz fight was already showing some signs of slippage even though he clearly won that fight. More interesting would be if 1998-99 version of Roy carefully bulked up to 200 lbs. In that case, i would slightly favour RJJ to win a decision. But 2003 Jones vs 1985-86 Holmes? I think Holmes catches him with a good right hand and stops him.
