Dorian would wipe the floor with Arnold on a BB stage, based on their respective physiques.
Can't base it on "if Arnold had the drugs".....
I have to disagree. The kinds of drugs available, supplements, dietary knowledge, judging criteria all changed between Arnolds era and Dorians.
The kinds of people who become great in a given activity have the kinds of character traits and personalities that would make them successful in any other era.
It's not realistic to think that the difference in drug protocols wouldn't help arnold be competitive in Dorians era. Also the expectations changed. If it were necessary to be 275 lbs in contest shape in order to win I think Arnold would’ve been able to achieve that with drugs, supplements and diet.
Conversely if Dorian were competing in the 1970s he would probably do whatever it took to be competitive then.
However Dorians era prized size over everything else. I think this is something Arnold could accomplish. Putting on size , i think would be easy for a prime Arnold. But in the 70's where aesthetics, peaked biceps, a vacuum were important but legs and back weren't prioritized in judging, Dorian would have a harder time. Back and legs were 2 of his strengths and they just weren't that highly judged while large peaked biceps and huge chest were judged highly are 2 areas that Dorian lacked.
