The former WWE champion, in an interview with Fox Sports, said that if he was offered a part-time contract he would not have quit the company.
"Now back in 2006, they weren't handing out part-time contracts at the time. I mean, I wish they would have, but they weren't," the 48-year-old wrestler said.
The soon-to-be WWE Hall of Famer said that Shawn Michaels and The Undertaker received part-time contracts, but it wasn't an option for him because he had been with the company for just six and a half years.
Angle regrets that he did not stay for two more years in order to get himself a part-time contract that the company started to rollout to wrestlers. He said to become a part-timer one had to put in 20 plus years. He added that he could have become a 25-time world champion if he had stayed after 2006.
"What's crazy is two years after I left, they started doing that. It was like 'damnit! I just missed it by two years.' I would have stayed in WWE. I went to rehab back in 2006 and I got myself straight, took Vince McMahon's advice, and I would have stayed."
"I wanted to stay, I just knew I couldn't do that schedule. At the time, unfortunately, it wasn't an option to be a part-timer, and I do understand it, because I was only in the business at that point for six and a half years," he said.
