Come Olympia day Robby was smooth. In 1979 Mike did give Frank a run for the money but its not like Mike was a clearly better and should have beat Frank. In 1983 there is no way Bertil should have beaten Samir. Bertil was big but not in the shape Samir achieved. He is narrow in the shoulders and posed for shit. Samir was a world beater on that day.
I always felt the younger (late 1960's / early 70's) Zane was pretty impressive - he packed pretty thick, dense muscle on his small frame. But as time went on (late 70's / early eighties), his physique lost that quality. I have heard that he supposedly had to largely forgo the power movements and train much lighter in later years due to injuries. I don't know how true that is, but his physique in later competitive years looked somewhat frail and swimmer-like IMO when compared to the more herculean guys like Robinson, Mentzer, Viator, Coe, Fox, etc. In his later competitive years he was not at all what I would consider an ideal Mr O type of physique to be.
I felt somewhat the same way (to a lesser extent) about Bannout. He had a great back, good overall aesthetics, and was rock hard in '83. But his relative lack of overall size and freakish propotions (other than the back) when compared to a mass monster like Fox (who was also quite hard and had much better proportions than most of today's big-bellied "mass monsters") wasn't really what I thought / think about in terms of a "Mr Olympia" type physique.
But Bannout was much closer to my subjective opinion of an "ideal" Mr O type physique than Zane or Dickerson were, and he was definitely at his alltime best in '83. I'm not familiar enough with the finer points of judging to comment on how much posing affects placing, but I would have a hard time placing Fox any lower than 2nd (if not 1st) that day (if I had been a judge). As for Fox's shoulder width, I don't recall Bannout having a particularly wide shoulder structure either. Bannout's back was definitely better overall of course.
