He wasn't his best, but he was better than everyone else there that day. Mentzer had zero chest development, and came in 5th, he shouldn't even complain. Zane was bad due to an injury. The only guys who came close were Coe and Dickerson. But Arnold was in such great shape, even if he wasn't his bigness, that he deserved the win. Whenever I see the contest or pics, I don't see why people make such a big deal. He was the best there that day.
