^^all depends on there fighting ability doesnt it? put 50cent up against antonio barrera and i bet barrera wud win why? because he actually knows how to fight.

rocky marciano was a very small heavyweight infact today he wudnt even be classed as one, he was knocking every fucker out.

roy jones jnr = small VS john ruiz (big fucker) who wins roy jones.

size doesnt always mean they are hard as fuck.

as for ja rule vs 50cent none of you know there fighting ability so you pick the obvious choice whos bigger and more gangster lol.
