Each circle marks a team’s location and is sized by the number of wins against the team to which it is connected (a rivalry)
These two teams orginally played across town from each other in Brooklyn and New York City beginning in the late 1800s. Their ability to remain foes after a cross-country move and keep the balance has led to this being called one of the greatest rivalries in sports.
The oldest in the NHL, the Leafs-Habs rivalry is symbolic of a country divided: the Quebecois Francophones against the Anglophones of the remainder of Canada. The two largest Canadian cities have won the most Stanley Cups of any team, facing off for the cup five times.
While not the most contested in the NBA, this rivalry involves two of the league’s most storied teams. They have met a record twelve times in the championship series, while their combined 33 trophies account for almost half of the 68 in NBA history.
Known as the Banjo Bowl (when played on Labour Day) since 2004, this rivalry is older than the Canadian Football League itself and extends far beyond the field, fueled by traditional competition between the two prairie provinces.
The longest-running in the NFL, this rivalry began in 1921 and is characterized by the balance between the two teams. The mutual Chicago- Wisconsin hatred has sparked similar rivalries in the MLB and NBA, as well as at the collegiate level.
