Strydom, Dearth, Robinson, Aaron Baker and others that still had some time left, ruined their careers.
The Quinns, Padilla, Ferrigno, etc were pretty much done, and made some quick bucks.
Eddie Robinson would beg to differ. When he got his MuscleMag column, he explained that he made more money in 1 year in the WBF than he would have in four years in the IFBB.
Plus, Eddie stayed an extra two years, endorsing ICOPRO, after the WBF folded. If McMahon kept him at his WBF salary, Robinson was making somewhere around $200,000/year.
Dearth and Baker did quite well and competed at several Olympias. Ferrigno managed a 10th place spot at the '93 Olympia.
Gary Strydom hardly ruined his career. Basically, he got spoiled rotten for two years as WBF champion (He was the first bodybuilder to get $100,000 for winning a pro bodybuilding show). Plus, he got a nice Weider contract (without even competing) shortly after the WBF went belly-up.
