Both Padilla and Platz were great, and got screwed many times over. 80 was Mentzer's. At least Platz had notoriety, and publicity, made a good living off the sport being a peoples champ. Padilla got nothing, all his scenes in Pumping Iron got cut too.
I'm not sure if Mentzer was always one or two short of a six-pack(like most geniuses & philosophers), but this whole 80 fiasco must have put him over the edge(along with some "mind-enhancing supplements").
