Bob Armstrong (70's)
Buddy Rogers (40-50's)
Billy Graham (pre-WWWF)
Favorites of mine but not on the list
Brian Pillman
Butch Reed
Buzz Sawyer
This was the best PWG Cena match ever. Callbacks to some of his best matches too (Punk RAW match, Owens, Umaga). I would have love to see Cena bleeds after the turnbuckle shots.
Killer Karl Kox
One of the great brawlers of the 1960's and 1970's. We can see a lot of Kox in Dick Murdoch (they even share the same finisher) as he was his mentor. Hurt by lack of footage.
vs The Destroyer (7/25/75)
vs Dick Murdoch (12/9/76)
vs Giant Baba (3/3/81)
Rewatched the Londos-Shikat (at the time I was watching everything about Dick Shikat, he was fascinating) and Londos looked good here.
All the footage are imcomplete (the Nagurski bout is listed as a 47 minutes match in the NWA book).
