Ed Comeau is the former head coach of the Orlando Titans, until they folded in 2010, of the National Lacrosse League. He is currently an assistant coach with the Colorado Mammoth of the NLL. Comeau began his NLL coaching career with the Toronto Rock, as an assistant coach under the legendary Les Bartley. The Rock won four NLL Championships under Bartley. In November 2003, Bartley stepped down due to his battle with colon cancer, and Comeau was promoted to interim head coach. However, less than four months later, after a 2-4 start, both Comeau and interim GM Derek Keenan were fired by the Rock, replaced by Terry Sanderson. In 2004, Comeau joined the Rochester Knighthawks as an assistant coach, and was then promoted to head coach at the beginning of the 2006 season, replacing Paul Day. Rochester finished with a 9-7 record, second in the Eastern division, but were eliminated from the playoffs by the Buffalo Bandits in the division finals. In 2007, the Knighthawks began the season 2-2, and then won a franchise record 12 straight games to finish the season with a 14-2 mark, tied for the best record since the NLL went to a 16-game schedule.
