Okay I am going to map this out. This is clearly my opinion as a fan of wrestling history who honestly loves Foley.
Here are the wrestlers clearly above Mick....there is no question IMO these guys are above Foley...this includes 41 wrestlers.
Jim Londos, Ed Lewis, Bronco Nagurski, Geroge Hackenschmidt, El Santo, Lou Thesz, Argentino Rocca, Verne Gagne, The Super Inteligent Destroyer, Rikkidozan, Buddy Rogers, Bobo Brazil, Whipper Watson, Killer Kolwalski, Georgeous George, Giant Baba, Bruno Sammartino, Andre "The Giant", Giant Baba, Mil Mascaras, Harley Race, Blue Demon, Nick Bockwinkel, Ric Flair, Jerry Lawler, Tatsumi Fujinami, Bob Backlund, Randy Savage, Antonio Inoki, Tigermask (Misawa) Dusty Rhodes, Jushin Liger, Terry Funk, Hulk Hogan, Roddy Piper, HBK, Bret Hart, Undertaker, Steve Austin, The Rock, John Cena, Brock Lesner.
Here is where Foley fits in....These are the wrestlers Foley is on par with. Here is another 44 wrestlers who are questionably better or worse all time.
Farmer Burns, Stanislaus Zbyszko, Joe Stetcher, Dick Shitkat, The Crusher, Earl Caddock, Pat O'Conner, Gene Kiniski, Dorey Funk Jr., The Great Gama, Mad Dog Vachon, Abdullah The Butcher, Karloff Legarde, Gory Guerrero, Billy Graham, Jackie Fargo, Kerry Von Erich, Ivan Koloff, Ricky Steamboat, Ricki Choshu, Sgt Slaughter, Mr Wrestling 2, Jimmy Snuka, The Great Sasuke, Iron Shiek, Ultimo Dragon, Perro Aguayo, The Great Muta, El Canek, Sting, Kevin Nash, Scott Hall, HHH, Vader, Dr Wagner Jr., Konan, Ultimate Warrior, Kane, Eddie Guerrero, Rey Mysterio, Goldberg, Jake Roberts, Kurt Angle, Randy Orton, CM Punk, Roman Reighns.
So at best IMO Foley is the 45th-95th best all time, but realistically he's more like the 70th best.
