Without getting into particular order.....Flair, Hogan, Dusty Rhodes, Steve Austin, Randy Savage, Andre, Harley Race, Sammartino, Buddy Rogers, Lou Thesz.....
Next 10 (no certain order).... Terry Funk, Sting, Cena, Nick Bockwinkle, HBK, HHH, Stan Hansen, Verne Gagne, Brett Hart, Undertaker.
There are a lot of guys who are close including Kevin Nash, Gorgeous George, The Road Warriors, The Freebirds, Midnight Express, Piper, Fritz Von Erich, Ted DiBiase, Jerry Lawler, Arn Anderson, Bob Backlund
Mount Rushmore would be 3 faces....Hogan (public face of WWE's national expansion, single biggest wrestling attraction all time, main event star in three decades)....Flair (most revered by his peers, second only to Hogan nationally in the 1980s, main event attraction for three decades and still today a cultural touchtone for both athletes and entertainers).....Vince McMahon Jr (promoter who revolutionized the industry promotional style and business model, first billionaire wrestling owner).
Again this list was based on careers which includes longevity and contributions as a main event performer. There are a lot of guys who had nice runs for brief period but over all it's hard to say they were all time contributors, such as Edge, Kurt Angle, Mick Foley....Lex Luger had a HOF worthy career but I don't think he reached the heights in most cases and/or matched or exceeded the longevity of the ones I listed in the Top 20 but he's real close....I chose against The Rock for the same reason I didn't include Ultimate Warrior & Goldberg....all three reached a Zenith that was unreal, but it was short lived and they had no real longevity. Goldberg & Rock chose to leave for other projects on their own or I think they both would have made The Top 20, Warrior's career just fizzled post 1991 but from 1988-90 he was about the hottest thing on the planet. Still, when I look at someone like Terry Funk who wrestled every style imaginable all over the US, Japan, and South America and lasted 40 years as a top attraction I cant rank someone like Warrior ahead of him. It's like a singer who has one song that is mega huge, the biggest of the year, but it's his only hit while another guy scores multiple Top 10 hits over several years....who had the better career ??
Plus, some on this list not only made huge contributions in the ring but behind the scenes as well such Von Erich, Gagne, and to a lesser extent HHH & Rhodes.
