Biggest pro football accomplishments: Played offensive lineman for the Los Angeles Rams for three seasons and appeared in Super Bowl XIV before being forced to retire due to a patella tendon rupture
Biggest pro wrestling accomplishments: Won the WCW World Heavyweight Championship three times and was involved in major feuds with Shawn Michaels and Undertaker in the mid-1990s during his time in the WWE
The key to his career change: He was encouraged to wrestle by someone who saw him working out in a gym shortly after his NFL career ended.

Throughout his career—which has lasted almost 30 years now—Vader has enjoyed varying degrees of success. He's been everything from a headliner towards the end of his WCW career to a jobber during his final days with the WWE. But Vader has worked consistently due to his imposing frame—he's 6-foot-5 and weighs more than 400 pounds—and his larger-than-life personality. He's never been the most popular wrestler amongst fans. But since retiring from football, he has fought for a variety of different wrestling organizations (American Wrestling Association, New Japan Pro Wrestling, etc.) and worked steadily both in America and abroad.
