best of the 80's? hard to say. 80s wasnt very exciting in bodybuilding.
Not so much "best", but "most impressive". For example, I would say that Markus Ruhl was more impressive than Shawn Ray but that's not to say I think Markus was better, since there's more to bodybuilding than simply impressiveness.
But when we're talking about dense muscle just popping off a bodybuilder's frame and conditioned from head to toe, I think Rich definitely qualifies, and while Lee Haney may have been better, he lacked a lot of the qualities that made Rich as impressive as he was - or at least lacked them in comparison to Rich, much like Rich lacked the stature and shape of Lee.
