In terms of training, Sgt. Buddy Lee Parker is easily in the top twenty-five ever, but in regards to in-ring accomplishments, we realize that is a stretch to put him on here even if we were the extend this list to 2,000. 

Gladys Gillem was one of the great early female wrestlers of the first half of the 20^th Century where she was often an opponent of Mildred Burke, who was the leading female attraction of the day.  Burke needed a new foe, which was Gillem and as she was on the losing end of the ledger she never received the notoriety that she should have.

Joe Savoldi had a claim at one time as the World Heavyweight Champion, which was a long way away from his humble beginnings in the hills of Italy.  Savoldi immigrated as a pre-teen to Michigan and would later play football under the famous Knute Rockne at Notre Dame.  Savoldi fell into Professional Wrestling and was praised for his dropkick, a unique move at the time.  Under the guidance of Billy Sandow, he beat Jim Londos in controversial fashion (perhaps a double-cross) in 1933 and was recognized in some circles as the Heavyweight Champion.  He would lose that claim in a match to Jim Browning but had high profile rematches against Londos to huge crowds.  He couldn’t beat Londos again but he was a draw for a decade and a half to come.

One of the most natural adoptees to professional wrestling in New Japan history, Masakatsu Funaki eschewed being one of the best Japanese pro wrestlers to become a pioneer in Mixed Martial Arts.  Funaki would leave New Japan and later co-found Pancrase with Minoru Suzuki wherein the late 90's he was considered one of the greatest fighters in the world.  After a loss to Rickson Gracie in 2000, he retired from fighting but would come back and later return to pro wrestling after a long absence, and he became the All-Japan Triple Crown Heavyweight Champion.  In terms of MMA influence few are in his league but translating that to a WWE Hall of Fame induction is a hard sell.
