6. Barry Windham
http://www.youtube.com/watch?v=9Ui9Ihcv0bM The Four Horsemen is one of the most notable stables in wrestling history, and has gone through many guises, always with Ric Flair at the core. Despite iterations that featured the likes of Steve 'Mongo' McMichael and Paul Roma of all people, the 1987-1989 WCW version that was inducted into the WWE Hall Of Fame in 2012 is the one best remembered by many. Its members were Flair, Arn Anderson (who also featured in every iteration of the group bar one, when he was replaced by Curt 'Mr. Perfect' Hennig due to injury), Tully Blanchard and Barry Windham. The first three of these men have entered at least one Royal Rumble match (with Flair emerging victorious after spending over an hour in the ring in 1992), making Windham something of an odd one out amongst his peers. Originally wrestling in the WWE as the U.S Express tag team with his brother-in-law Mike Rotundo (who would later adopt the gimmick of I.R.S) in the eighties, Windham would return briefly in 1989 as the Widowmaker in between NWA and WCW stints. He would come back again in 1996 as The Stalker, before adopting the moniker of Blackjack Mulligan (his father being Blackjack Lanza) with Justin 'Hawk' Bradshaw (later just Bradshaw and then JBL), who would compete in the 1998 Rumble without his partner before departing for WCW once more. Despite never making much of an impact with his assorted gimmicks in the WWE, Windham's WCW career was a distinguished one, albeit one that obviously never allowed him to appear in a Rumble match. His two nephews Windham (named after him) and Taylor have however, competing as Husky Harris and Bo Dallas respectively in 2012 and 2013, and the former may make another appearance this year now that he is portraying the well-received Bray Wyatt character.
