The Three Stars:
Original Six Becomes Even Dozen - The largest single-season growth in National Hockey League history occurs when six expansion franchises take to the ice. The Los Angeles Kings, California Seals, Pittsburgh Penguins, Philadelphia Flyers, St. Louis Blues and Minnesota North Stars all begin by stocking their roster on June 6, with established teams allowed to protect only 1 goalie and 11 skaters. Los Angeles makes the great veteran goalie Terry Sawchuk the first expansion selection.
Bill Masterton Dies - Crunched by California defensemen Larry Cahan and Ron Harris in a game on January 13th, Minnesota forward Bill Masterton strikes his head on the ice and suffers massive brain injuries. The helmetless Masterton dies two days later. The Bill Masterton Memorial Trophy is introduced and awarded for dedication and excellence achieved in the sport of hockey.
Blockbuster Trades - The Chicago Blackhawks trade Phil Esposito, Ken Hodge and Fred Stanfield to Boston in exchange for Pit Martin, Gilles Marotte and Jack Norris.The Leafs also trade Frank Mahovlich, Garry Unger, Pete Stemkowski and Carl Brewer in exchange for Paul Henderson, Floyd Smith and Norm Ullman.
- The NHL is divided into two divisions - the "East" which features all of the Original Six teams, and the "West" which features all of the new franchises, even if they are in Eastern time zones. The playoff format ensured a showdown between the winner of each division, therefore guaranteeing the new franchises a chance to compete for the Stanley Cup.
