Maybe three of them deserved. 
Monster original response.
There has seldom been an Olympia winner without a controversial win or 2.
Scott...'66 (Sipes kicked his ass)
Arnold...'72 and '80 (Oliva and the rest of the top 5 in '80)
Zane...just ugh. (Particularly vs. Mentxer in '79)
Haney...'90 (Labrada)
Yates...'94 (Shawn and Levrone)
Coleman...2001 (Cutler), 2002 (Kevin and Gunter)
I know your comment was somewhat in jest, I just hato to see so many hate on the man after the fact... truth is, during his reign, even Nasser, Kevin and Shawn acknowledged that Yates would never be beaten on size and conditioning (1994 notwithstanding!).
