I had an argument with a coworker on who the biggest star to transition from Wrestling to MMA was and I felt it Ken Shamrock but he felt it was Lesnar.
Ken started out in Pro Wrestling in SAPW/NAWA in 1988 and then went to Shoot-Fighting in Japan before he went to the UFC and then tried his hand back in the WWF.
