Haney definitely deserves to have been Mr. Olympia, unlike several other "winners".
Lee didn't have anything that stood out, but as a whole physique, he was AWESOME. TotaLee awesome.
Plus, as has been said, the man is a fine man. I have shared dinner with him and he is classy, friendly and intelligent.
Whether he is the best is a matter of opinion. But without question is his superiority amongst a vast majority of bodybuilders who have competed as professionals in the IFBB.
I'd rank him as one of the O's greatest titleholders, no doubt.
In many ways, top level bodybuilding has only gotten worse since Lee's reign. The man carried a lot of muscle and presented it with desirable aesthetics. When you consider the limitations of what he likely took in comparison to what guys do today, he is remarkable.
Lee kicks ass.
