The 1980 Mr. Olympia is definitely the most debated contest ever. I just saw a video by Norm Komich recently and I can understand why it was so controversial. Norm was at the show and he filmed it from the balcony using his video camera. Arnold's legs were really down in size and there were a lot of guys who were in top shape. Zane, Mentzer, Coe, Walker, Callendar and Dickerson were all peaked and ripped. The fact that Arnold didn't let anyone know he was competing and he also had friends on the judging panel (Reg Park, Albert Busek, Mits) created a lot of resentment from all the top competitors. Looking at it from Norm's video (and not pictures, which don't always tell the story), you can see the big weakness in Arnold's legs. Although he still looked great for the limited amount of time training for the show, a lot of the audience and all the other competitors didn't feel like he deserved the victory because he had a glaring weak point (just like Franco did one year later). Like Zane said after the contest, when you have had a layoff that long and you only train for a couple months, the strong bodyparts (Arnold's arms, chest, back) are going to come back quick but his weaker muscle groups (legs, delts) are going to lag behind.
