So according to your logic theree is no discussion either between who is a greater bodybuilder between Ronnie Coleman and Dorian Yates, as the former has many more pro wins 
Purely from a statistical standpoint Ronnie is a greater bodybuilder than Dorian because he has more Olympia wins and professional wins , I don't have a problem with that it doesn't mean much in the context of Dorian-vs-Ronnie because zero of those wins are against Dorian

And you're missing the big picture win/loss ratio Dorian 88% vs Ronnie's 40%

Dorian was a winning machine never once placing below second place in a professional contest that's insanity not even matched to this day . from a statistical standpoint Dorian would beat Ronnie , especially considering he faced Ronnie 8 times and beat him all 8 times

53 contests for Nasser with just 6 wins that's a win/loss ratio of 11%
62 contests for Kevin with 20 wins that's a win/loss ratio of 32%
16 contests for Lee Haney with 11 wins that's a win/loss ratio of 68% never once placing below 3rd in a pro contest
