Nailed it. Overall, Dillet crushed Yates. Dillet's back is just an excuse, wasn't nearly as bad as the ownage visited on Yates by several tops guys in about 35 shots.
Dillet was HUGE. Yes. Was he as conditioned? No. Did he pose as well as Yates (or anybody?)? NO.
Contests are not judged solely on how big someone is, or just one thing. It's ALL the things combined (when the contest is properly judged that is).
Dillet couldn't pose worth shit,he would shake if he could hold the pose for more than a second, he was known to take too many diuretics which would flatten him out if not just make him become a living corpse getting carried offstage, and he had no back and certainly what he had he could NOT pose it for shit. How was his presentation? There was a competitor that I saw that had zero back onstage once. In the mandatories, he stood out like a sore thumb for not having any back. But in his solo posing, he looked good. Why? Because he didn't hit a single back pose, which hid this major flaw.
Presentation, muscularity, symmetry, conditioning....many things just from "being huge" are factored into whether someone wins a contest or not.
