Like his brother Lester, Frank Patrick was a decent player who became more famous in hockey for his off ice contributions than what he did on it. Along with his brother, he founded the Pacific Coast Hockey Association (later renamed the Western Canada Hockey League) and it was many of his initiatives while there that shaped the game as we know it today.

Considered one of the best all-around Canadian athletes in the turn of the century, Dan Bain excelled at everything he touched. Consider that he won the following:  

The Manitoba Roller Skating Championship at age 13
The Manitoba Gymnastics Competition at age 17.
Three Manitoba Cycling Championships.
Canadian Trapshooting Champion in 1903

It is very possible that Art Ross may have done enough to enter the Hockey Hall of Fame just for his on ice endeavors, or even enough on his off ice ones. Seriously, he was that important to the game.

A very important figure behind the scene in the growth of hockey (especially in Montreal), William Northey helped to establish the ECAHA (Eastern Canada Amateur Hockey Association) and later the CAHA (Canadian Amateur Hockey Association). Northey helped to convince Sir Montagu Allan to donate a trophy (The Allan Cup) which was (and still is) given to top Amateur team in Canada. He would become the Cup’s trustee. In Montreal, he was the director of the Canadian Arena Company which built the iconic Montreal Forum.
