Why didn't Samir Bannout accomplish that after his 1983 Mr. Olympia win?
do you mean the judging standard bit?
I think due to never being able to duplicate 83 shape. Also some youngster from Atlanta, Lee-something... had the best and biggest physique at the time, 84-86 were his, 87, 88 Gaspari couldve done it, but difficult for a new young pro, no matter how good, to come out of nowhere and nab it from a reigning Olympia(ask Levrone). 89, 90 Labrada.
But in 84, Haney couldnt be denied.
