The video features the men who've run the NHL -- from Frank Calder, the League's first president, to current Commissioner Gary Bettman -- as well as father-son-grandson combinations (Lester, Muzz and Lynn, and Craig Patrick), as well as fathers and sons including the Selkes (Frank Sr. and Frank Jr.) from the NHL's earliest days to modern day pairings such as the Bowmans (Scotty and Stan) and the Fletchers (Cliff and Chuck).
There are also brother combinations, including the Espositos (Phil and Tony), and a picture of the League's 31 general managers taken on Nov. 17, 2017, to commemorate the 100th anniversary of the NHL's founding.
