The 2007–08 Calgary Flames season began October 4, 2007. It was the franchise's 35th season in the National Hockey League, 27th season as the Calgary Flames. In a surprise move, the Flames announced on June 14 that Jim Playfair would be replaced by "Iron" Mike Keenan as the team's head coach. Playfair remains with the Flames as an associate coach. Keenan entered the season 6th all-time in the NHL in wins. Keenan also captured the Jack Adams Award as the NHL's coach of the year in 1984–85 with the Philadelphia Flyers. On December 16, Keenan recorded his 600th career win as a head coach in a 5–3 victory over one of his former teams, the St. Louis Blues.
