When you think of top rivalries, you may think of the Bears and Packers. Maybe the Bulls and Knicks back in the day. Duke and North Carolina. Michigan and Ohio State. Magnus Carlsen and Hikaru Nakamura. Why does the USA-Canada rivalry in women’s ice hockey have a claim to the best of them all? They’re always in the final. The Olympics have had seven women’s hockey tournaments. The USA and Canada have faced off in the final six times. (Canada has won four of those and took the gold when the USA settled for bronze in 2006.) Women’s hockey has had 23 world championships. The USA and Canada have played each other in the final 22 times. (Today makes it 23 of 24. Canada holds the edge, 13-9, and the USA won a 10th when Canada missed the final in 2019.) These teams have immense respect for each other, and the players are working together to establish pro women’s hockey at a serious level. But these games can get rather chippy as well. Best rivalry in sports? It’s certainly in the running. (And yes, political intrigue adds a new wrinkle this year, but this game is in Czechia, so the vitriol in the stands should be minimal.)
