Chicago Cougars

The Chicago Cougars were an original franchise in the World Hockey Association from 1972 to 1975. The Cougars played their home games in the dilapidated International Amphitheatre. During the 1974 Avco Cup Finals against Gordie Howe and the Houston Aeros, the team's two home games were played at the Randhurst Twin Ice Arena in suburban Mount Prospect. This was because a presentation of Peter Pan starring gynmast Cathy Rigby was booked into the Amphitheatre and thus made the arena unavailable for the playoffs (see Peter Pan Incident, below).

Just prior to their third season, the team was sold to Cougars players Ralph Backstrom and Dave Dryden, and player-coach Pat Stapleton after the original owners, Walter and Jordon Kaiser, were unable to secure funds to build a new arena. The land for the arena, originally named the O'Hare Sports Arena, was sold to the village of Rosemont and became the Rosemont Horizon (now the Allstate Arena). This building is the now the home of the Chicago Wolves of the American Hockey League.

They were placed in the Western Division for their first season (1972–73) and transferred to the Eastern Division for their final two seasons (1973–74 and 1974–75) when the Philadelphia Blazers moved to Vancouver.
