In an unsurprising development, the Hall of Fame voters continue to agree with the TPAK results to a greater degree as time goes on, and as they get into players they had the greatest chance of being directly familiar with. In the case of players whose careers were centred in the 1920s (see table below), we find the top 17 players (and 19 of the top 21) have actually been inducted into the Hall of Fame. The only ones that have been missed out are Carson Cooper and Corb Denneny.
Carson "Shovel-Shot" Cooper was a dominant scorer for the Hamilton Tigers of the OHA in the early 1920s, leading his senior league in goals three times and points twice; in 1923/24 he scored 33 goals in 10 games and finished his OHA career with 108 goals in 55 games. Signed by the Boston Bruins in November 1924, it didn't take long for Cooper to make an impact in the NHL. In 1925/26, he finished second in the league in goals, behind only the legendary Nels Stewart, and was third in points. In 1928/29 he was in Detroit (and 32 years old), and though his raw numbers were less impressive (due to the scoring environment of the league at that time), he was third in goals and tied for third in points.
Cooper is found deserving of the Hall because his OHA numbers are not ignored. He had only two NHL seasons among the best scorers, but it must be remembered that he didn't play his first professional game until the age of 27. This means his NHL career was played mostly in the decline phase of his career. Point Allocation, however, doesn't pretend that the NHL is the only league that matters at this time of the game's history. So Cooper's thoroughly impressive OHA production is given the full credit it deserves.
Corb Denneny, lesser-known than his Hall-of-Fame brother Cy, had a 19-year senior/professional career. Though never the best centre in his league, his consistency and longevity are what earns him Hall-of-Fame-level merit here. Being just below the very best for an extended period of time is quite remarkable in itself.
I see every player listed on the table below as deserving of being in the Hall of Fame, based on their TPAK results. And speaking of longevity, check out George Hainsworth's career. He managed 1611 effective games played, which is the equivalent of playing a full 80-game schedule for 20 seasons, plus a bit. Hainsworth played his first senior hockey in the OHA (at the age of 17) in 1912/13, a full 11 years before he would play his first professional game. After 11 seasons of senior-level amateur hockey (all but one of which was played in Berlin, later Kitchener), he began a 14-year major-pro career, retiring at the age of 41. Like Cooper, Hainsworth gets credit for this time in the OHA, which was a high-quality league at the time and cannot simply be ignored because it was not professional.
