That would be on Vince's fetishes not the crowds. Dusty was still doing very well with the NWA after Vince brought Hogan back to his promotion in 1983 and made him the top guy. Steroids were around in wrestling since at least the early 70s, probably earlier and Dusty feuded with the grand father of the steroid era in Superstar Billy Graham, main evented MSG twice against him when Vince Sr. Was still running things, the crowd wouldn't have cared. Hell, Hogan had multiple feuds with guys who were very overweight "monsters" who had a fraction of Dusty's charisma or talent. Of course those big guys weren't the face of the company but Dusty would've done mostly fine had he came up in the 80s, he probably would've had a different look but probably at Savage level as the number two or three behind Hogan. Hell, when Dusty came to the WWF with Vince running things he was past his prime and despite the horrible look and those unflattering polka dots Dusty was still very popular.
