1. Clarence Cambell
As League President from 1947-1977 Cambell was the man in charge during hockey’s “golden era’. He was crucial in overseeing the original expansion from 6 to 12 teams and up to 18 by the time he retired. He fought off the threat from the WHA ensuring that the NHL remained the Top league. And most notoriously he suspended the Rocket and had the guts(or stupidity) to show up to the next game leading to the Richard Riots. Through good and bad he set the leagues path for 30 years.
2. Al Eagleson
His influence is undeniable despite all his wrongdoings.
3. Bobby Orr
On the ice: he completely changed the way defence is played. He is still the greatest defenceman to ever play and off the ice he was and still is a major play in NHL labour relations.
4. Vladislav Tretiak
I had trouble choosing between him and Patrick Roy. Tretiak was the innovator of the butterfly style but Roy perfected it and led it to be the most dominant goaltending style in the game. I give Tretiak the nod only because in addition to the butterfly he backstopped the Russians in the 72 summit series which redefined how Russians and other Europeans hockey nations were viewed by North Americans.
5. Gary Bettman
While I agree he is hugely influential in shaping the NHL today I don’t think his true influence will be known till long after he is gone. It will be interesting to see how well his sunbelt expansion holds up over the next 10-15 years.
6. Foster Hewitt
The voice of Hockey Night in Canada. Hewitt brought the game to people across the country who couldn’t afford to go to a game or lived to far away from any NHL clubs. His influence is still evident anytime you hear an announcer say “He shoots He scores”.
7. Bobby Hull
Aside from being a prolific goal scorer Hull made his biggest influence on the NHL by leaving it. By signing a than unheard of 1 million dollar contract with the WHA Hull ushered in an era of exploding contracts leading eventually to the lockout of 04-05
8. Börje Salming
The first European star of the NHL. Salming paved the way for the wave of Europeans to make their way across the pond to play in the NHL. Followed by the likes of Jari Kurri and Petr Statsny, Salming led the way to the NHL being the truly multinational league it is today.

9. George Hainsworth
22 shutouts in 44 games. That amazing feat will never be matched mainly because it was the spur of the biggest rule change hockey has ever implemented the introduction of the forward pass. It is hard to imagine hockey without the forward pass so it is easy to overlook how important this change was but it all started with Hainsworth’s unbelievable feat of 22 shutouts in a single year.

10.
Left blank because I can’t think of a forward who was changed the way his position was played. Bobby Orr changed the way defence was played. Tretiak and Roy changed the way goaltenders play. But in my mind there has never been a player to truly change the way forwards play the game. Sure, Gretzky played differently than everyone else but he didn’t influence his position like Orr. No one who came after Gretzky could truly emulate him because his skill was just too high. Other players have all followed in the footsteps of those before them none that I can think of really changing the way the game is played quite like Tretiak, Roy and Orr did. Maybe there is someone but I can’t think of anyone so my tenth spot is left for the next great innovator who changes the way forwards play the game of hockey.
