This was actually the first bodybuilding show that I ever attended. I went in pretty sure that Yates would win easily, but Shawn Ray was just amazing that day. Yates had raucous support from the audience, of course, but when Ray was going through his compulsories, you could hear a pin drop, save for the intermittent (and perhaps cliched) "audible gasps". He had amazing things happening in his back musculature, in particular.
My father was with me that day, and he thought that Nasser won, hands-down. I thought Yates looked better than Nasser overall, but I just couldn't believe how sharp Ray was. The two physiques (Ray and Yates) were so different that I thought a win by either would have been acceptable, BUT it was a little strange that Yates and Nasser were separated in the placings. When compared to those two, Ray was such a different animal that day that it's hard to imagine how he didn't finish either first or third.
