The photo in the OP is incredible to be sure, and I prefer Dorian's physique to Coleslaw's any day but remain a fan of Reeves, the Oak, Park, Draper, Pearl, Zane, Nubret and Paris in about that order. Bodybuilding is highly subjective. For example I think Levrone is another competitor that is superior to Ronaldo the Obese with Shawn Ray also presenting a more aesthetically pleasing and proportionate physique than Gutler or Coleslaw to name two recent fatasses of the dais.
But Yates was good, very good indeed. Better than Sir Ronald of Coleslaw? Subjectively so. Others think differently, as is their right.
