The problem for Dorian is at his career best, which may be 95 or 97,depending on the criteria for ''best'', and who you ask, he had a torn bicep, his back and front double bicep's weren't that great, 'compared' to the other competitiors. Thats not to say his poses from front werent good. Just the biceps. But his mass and granite-like conditioning, is arguably best ever. And his abs at that weight is rediculous. So, leave him out, or put him in top 5? Those back shots of Dorian are some of the best of all time. He looks skinless!
But Ronnie Coleman, with his crappy calves doesnt seem to be an eyesore. But overall seems to have good muscle shape and excellent biceps. In fact his arms are probably the best ever overall. Even at 2006 mr olympia they still looked awesome, but overall he looked like shit, at least on stage .. 1996 or any other Coleman would kill 2006 Ronnie based on conditioning[body-fat, seperation, and water, also abdominals] and everything ..
So, at their best i would put it:
Ronnie Coleman 1998
Paul Dillett 1994
Dorian 1995
Arnold 1974
Jay Cutler 2001
This just my opinion. If someone considers the physique with crappy hamstrings, but good arms and back ''not so good'' then Arnold would be number 5. If other consider best conditioning, and mass but poor biceps, then Dorian would be fifth, or coleman without calves and so on. So this is just mine, but even still im not so sure if you asked again. Truth is they're all good in their own way.
