From the list, I picked Levrone. Overall, I have Nasser ahead of him. I think it was 96', he looked phenomenal! He had the slabs packed on him. Came in hard. Not sure why he didn't beat Yates that year, and this is me saying it as I am a big fan of Yates. We all have our own eyes. Levrone is 2nd on the list for me. He always had looked good then Ray and Wheeler.
I went with Robbie too. He had one of the most perfect physiques I have ever seen til this day. I meet him a Golds's Gym Venice in 84'. He was super personable to young guys coming around asking questions. You should check out his autobiography:
Miike Mentzer should have beat Frank Zane in 79 and Arnold in 80. The guy would be considered small now, but at the time, no one could compare to his thickness and density. I was 12 or 13 at the time and it was obvious to me just from looking through Muscle and Fitness magazine. ( might have still been Muscle Builder then)
