The pencil neck is getting totally smocked in this shot. Yes Flex had more shape and definition to his back but at the end of the day Nasser was a SHW while Flex was in the middle weight category, looking like a child next to Nasser. His only really big body part was his SEOed biceps.
ALSO! Flex clavicles were very short, even shorter than Phils, but since his head was the size of a peanut it gave the illusion he was wide when posing alonge. But then this smoke and mirros end when you put him side by side with any legit heavy weight. Thats why Flex never won a Olympia and never would even if he competed for a thousand years.
Flex didn't win the Olympia because of a multitude of reasons , timing was one of them , if not for the car accident and if he was 100% on in 1994 he could have beaten Dorian , perhaps the same in 1997 , Flex was doing all the spring shows in 93 so his body was screaming for a rest by the time the Olympia rolled around.
Nasser in some shots owned Flex , but when all is said and done , Flex outclassed him.
