Ken Shamrock

I was watching a interview where Ken said he wants a WWE return but for some reason, they never get back to him. It got me wondering, why havent they brought him back? Did he leave on bad terms?

​The question actually came up on Observer Radio a few weeks back, and the basic answer seems to be "No one's sure".  It's not like Ken was fired and drummed out of the company or anything, but you'd think Ken would be a shoo-in for the Hall of Fame or whatever and yet Vince never seems to want to use him.  Vince gonna Vince, I guess.​
