Considered by his peers and experts to be an exceptional wrestler in terms of wrestling ability and ring psychology and with the ability to cut an eloquent promo, he was one of the faces of AWA/NWA having won over 29 titles.
He also fought in a AWA-WWWF inter promotion title unification match with Backland which ended in double count out. He is however mostly known for St Paul Screwjob (Yes, Montreal Screwjob had a precedent) where Hulk Hogan pinned him for the championship but the decision of the referee was reversed, one of the reasons why Hogan moved to WWF.
Having never wrestled for WWE he never would get the due recognition for his 32 year career.
