genetics. Even his 'buddies' like Dorian Yates said this when asked who of his generation had the best genetics. I wonder how Flex responds to this as every Tom Dick and Harry says that he is amazing but he never made the best of his potential...
Dude, he won multiple top-tier shows - Ironman, Night of Champions, Arnold x 2......Your definition of making the best of one's potential must be winning the olympia......fair crack of the whip mate!.....but so be it.....HOWEVER, in my eyes, his 1993 Arnold shape was amazing.....a beautiful & powerful package.....and in that regard he reached his potential....he became the best he could.....actually, he was that good that it moved Arnold to say it was the best physique he's ever seen on stage (recalling from memory).....unfortunately at the 1993 Olympia, he came up against Dorian who had that something extra.....sh*t, what can you do....some one is always better......
Another thing, you're forgetting the car accident that nearly killed him....that put him out of action and screwed him up good....put him behind the eight ball big time....then the dumb shcmuck tried to play the catch up game with synthol.....that is my opinion was the end of Flex....he lost the natural sweep, the beauty, the wonderful lines.....so its not like he didnt become the best of the best because of laziness or lack of drive, or whatever......he got thrown a curve ball by life (a big one at that) and the shcmuck missed badly....
anyway, its all hingsight now isnt it....
