Buddy, Arnold wasn't close to bigger than everyone else that night. He was as light as he had been since what....'69? Mentzer was shorter, about a mile thicker, with cross striations on his triceps and legs 2x the size of Arnold's. Arnold wasn't as proportional as Zane, Dickerson, or Mentzer. He wasn't as big as half the lineup, and he was probably only on par with their conditioning. All this combined with the fact that he was Arnold and the judging panel was made up not only of his friends, but former roommates, and role models=biased judging.
