Does anyone seriously think Boyer Coe was better than Mentzer at that show?
No, and I certainly don't think Arnold's legs were better than Mike's

Mike was flat, but he should've probably placed second or third. I really don't care for Dickerson's tiny, droopy pec, puny arm build. And Zane was cut (hahaha ... get the reference? He cut his member! Haha ... ha

), but nowhere thick enough to challenge Mike's density.
I do agree with Arnold winning, though. The only reason people piss on his victory is, well, actually two reasons:
*He was a late entry and made a stink about weight classes
*He wasn't as good as he was several years before
That's it. Even at a lighter bodyweight, he was still dominant.
