18. Rey Mysterio
While we expect most wrestlers to indulge in a bit of bragging, Rey Mysterio definitely took self-promotion too far. Indeed, the fighter began boasting to interviewers that he would make more money in his homeland of Mexico than with the WWE. Unsurprisingly, then, the company was not impressed. And, as a result, the star fell into the background. What’s more, his contract wasn’t renewed when it expired in 2015.
Nailz was known for his ex-con persona, and he was just as terrifying as his WWE alter ego in real life. In fact, the brawler was fired from the WWE in 1992 after an argument over money ended with him violently choking Vince McMahon. After losing his job, then, Nailz – real name Kevin Walchoz – left wrestling behind and instead opened a gas station in Glasgow, Scotland.
16. “Hacksaw” Jim Duggan
Although he maintained a healthier career than most wrestlers on this list, “Hacksaw” Jim Duggan still managed to ruin his chance at superstardom. Specifically, the American patriot was found with cocaine and marijuana in his possession during a 1987 traffic stop – an incident that got him arrested and subsequently fired. “I don’t think I ever regained the momentum I would have had before the arrest,” he told wrestling website PWTorch in 2012.
