Mark Giordano of the Calgary Flames

The Calgary Flames are a professional ice hockey team based in Calgary, Canada, that play in the National Hockey League (NHL) as a member of the Western Conference's Pacific Division. Founded in 1972 in Atlanta as the Atlanta Flames, the team relocated to Calgary in 1980. The Calgary Flames initially played at the Stampede Corral before moving into the Olympic Saddledome in 1983. In 1985–86, the Flames became the first Calgary team since the 1923–24 Calgary Tigers to compete for the Stanley Cup. In 1989, the Flames won their first and only Stanley Cup. The Flames' unexpected run to the 2004 Stanley Cup Final gave rise to the Red Mile, and in 2011, the team hosted and won the second Heritage Classic outdoor game. The Flames have won two Presidents' Trophies as the NHL's top regular-season team, and eight division titles. The Flames are one of two NHL teams based in the Canadian province of Alberta, the other being the Edmonton Oilers, leading to a rivalry known as the "Battle of Alberta". (Full article...)
