Lets first define the term "over-rated".....
Over-rated means that the person is percieved to be much better than he really is, or has proven thus far......
I don't think you can put anyone who has won the Olympia in this category....and guys that have won numerous pro shows are also not overrated....
I can tell you who I think is the most over-rated BODYBUILDER in history...easy one...not even a challenge.....
VICTOR RICHARDS!
Hard to not pick Vic when he has never even stepped on a pro stage, yet his loyal subjects have called him the "uncrowned Mr. Olympia" for years, now! Pretty big shoes to fill considering he has never won/ competed in the Nationals, USA, N.American, or World championships...
I even have it on good authority that he never even won his pro card in his native championships years ago.....as was originally thought.
Talk about over-rated....!
