6. Goldberg
Bill Goldberg is a bit like Kevin Nash, he has made no secret that pro wrestling was just a job. He did it for the money, which is exactly why he took so long to make a deal with WWE after WCW folded. Once that WWE deal expired after a year, he has barely been involved in pro wrestling in the eleven years since. He simply doesn't have the passion to compete, and no one has been willing to put up the money he demands. Goldberg was on two million dollars a year in WCW, and only came to WWE in 2003 when they offered a million dollars for part time dates. Before any of that, he'd been a footballer, and pro wrestling was just a fall back to make a bit of cash.
