The year was 1919 and the Seattle Metropolitans of the Pacific Coast Hockey Association (PCHA) were a very talented hockey team. They became the first American based team to win the Stanley Cup by beating the Montreal Canadiens (then of the NHA) in 1917.
They were all set to repeat the feat in 1919 and were tied 2-2-1 going into the sixth game when the Spanish Flu epidemic struck. Due to the mass illness, the decision was made to cancel the playoffs and the championship that year. Probably most disappointed was Seattle’s Frank Foyston who scored 8 goals in the first 4 games.
