What's sad is that we could easily go back to those standards simply by the judge's scoring decisions.
When the judges are actually scoring a show they would have to find the best 90s bodies. What constitues a 90s body? What if everyone in the show sucks according to the 90s aesthetics, what then. Maybe they could pick Bumstead from the physique category and have him be Mr O? Nah that wouldn't be satisfactory either. What would you do with a Nasser 90s body? It was full of oil, smooth as hell and blocky. Nasser would fit nicely beside Nick Walker.
I actually don't think it can be done. It's like grying to judge the females by requesting they be 20% smaller and soft. They looked worse and just as masculine and no one knew how to judge that shit.
I actually think they judge shows pretty much just the way they used to. Hell we have Weinberger still and probably other oldtimers.
