I remember when I was a kid seeing that. He even went on to say that it was a good thing that Arnold retired when he did. LOL. He couldn't even beat Arnold in 1975 when he was not at his absolute best. If Arnold didn't retire after 1974 and lost all that weight for "Stay Hungry" and only came back at the last minute to film "Pumping Iron", meaning if he continued training year round after his '74 win he would have been even bigger and better and crushed Franco even more. The pattern would have continue through through the rest of the 70s all through 83. I'm not sure how he would have stacked up against Haney as I'm sure age would start to take it's toll. I can't see him losing to Dickerson and Samir. That would be 13 Mr. Olympias.
Given that Arnold was still "Arnold", he would probably have stayed one more year and wiped the floor with Haney. There is no way on earth that Haney could have defeated the Oak and that's because of Arnold's pure superior genetics and an indomitable will to win simply by being the best he could be and in doing so, be vastly better than anyone else.
Haney was gifted a few wins as I think Labrada was better than him but like they said in the book "Pumping Iron" about the unwritten rule that a good big man will more often than not beat a good small man.
Arnold was the finest bodybuilder ever. Taking into account both drugged and natural, Arnold is it. Steve Reeves is the best built natural ever.
