Negro Casas came into Lucha Libre with an excellent pedigree as the son of Pepe Casas (and the brother of two other Luchadores), and he proved to be the most talented of the clan.  A natural from the start, Casas would win a plethora of championships in Mexico both as a single and tag team, and his rivalry/friendship with El Hijo Del Santo made them both for years.  The problem though for any potential WWE Hall of Fame induction is that Casas was not that successful outside of Mexico and did nothing of note in an American ring.

Phil Zacko is a name that doesn't come up much, but along with Gorilla Monsoon and Arnold Skaaland, Phil Zacko owned part of Capitol Sports which was the precursor to the WWE.  That triumvirate had half of the WWWF where Vince McMahon Jr. would buy out his father’s share and worked out a deal to buy the other half in staggered payments, which he was able to make.  Zacko was not just a co-owner but a principal promotor in Pennsylvania and essential to the Vince McMahon Jr. success of the organization.

Earl Caddock was one of the greatest amateur wrestlers of all time as he was a three-time winner of the National AAU (Amateur Athletic Union) title before becoming a professional.  Caddock would defeat Joe Stetcher for the World Heavyweight Championship in 1917 and would later beat Wladek Zbyzsko who won a tournament for the vacant title when Caddock refused to enter it.  He never won the title back but had classic matches against Stetcher and Ed “Strangler” Lewis in title rematches.  His career was short as he retired in 1922.

An Olympian in 1984, Hiroshi Hase would go on the New Japan where he first gained traction as their Junior Heavyweight Champion.  Hase would win that championship twice, but he would move up the ranks to heavyweight where he would be one of the promotion's top tag team wrestler winning the belts on three occasions, two with Kensuke Sasaki and one with Keiji Mutoh.  He would also have stellar singles matches as a heavyweight, most notably against Mutoh where Muta (he wrestled as the Great Muta in that match) bled so much in a match that the famed “Muta Scale” was created by fans to gauge how much crimson occurred in a match.  Hase would later wrestle for All-Japan and was unselfish by putting over a lot of talent.  He would then become a very successful politician in Japan.
