Mike Johnson of PWInsiderElite.com recently revealed why Kurt Angle doesn't wrestle more for WWE, Below is what Johnson had to say, courtesy of RingsideNews.com: 

"They’re not going to put Kurt in the ring on a consistent basis. He can’t do it. I am sure Kurt wants to be in the ring on a consistent basis. His body is breaking down." 

"Remember the last six months of Impact and then the couple of indie shows he was doing? It was the same five spots the entire match. He can’t be that Kurt Angle anymore. It’s like Shawn Michaels saying 'I could come back but people need to understand it’s not going to be HBK.' It’s not fair to expect the Kurt Angle of 1999 to be wrestling."
