Selected with the Kelowna Rockets second round pick, 35th overall, in the 2001 WHL Bantam Draft, Blake Comeau started playing with the Rockets as a 16-year-old. In 2003, Comeau was selected to play for Team Canada in the 2003 U18 tournament in Yaroslavl, Russia, in which he and his teammates brought home the Gold Medal. During the 2003-04 regular season, he played with Edmonton Oilers prospect Troy Bodie and 2004 draft eligible prospect Tyler Spurgeon to form the 'Network Line'. In the playoffs, Comeau was able to help the Rockets win the Memorial Cup in front of their own fans as the host team.
Comeau was chosen by the New York Islanders in the second round, 47th overall, of the 2004 NHL Draft.
Many Kelowna Rockets fans and WHL scouts expected Comeau to score a little more than he did in 2003-04, and while he certainly did not have a poor season, he has the ability to score much more than he has in the past.
2005-06: The Islanders top CHL prospect had what one could be considered a banner year in the Western Hockey League and internationally. The second round pick in 2005 put up solid numbers in every category with 21 goals, 53 assists for 74 points in 60 games, eclipsing his personal best by 27 points. He finished in the top 20 in the WHL in scoring.
Comeau also helped lead Team Canada to a gold medal at the IIHF Under 20 World Championship, leading the team in points and was a key player for Head Coach Brent Sutter in all situations.
Comeau’s year did not go unnoticed by Islander brass. Comeau was signed to his first NHL contract in March.
2006-07: Comeau was another one of the Islanders prospects to spend time with the Islanders and Sound Tigers last season. He saw three games with the Islanders, scoring no points and no penalty minutes. However, in 61 games with the Sound Tigers, Comeau collected 12 goals, 31 assists for 43 points to go with his 46 penalty minutes.
A multi-dimensional player, Comeau is a very smart puckhandler with strong offensive instincts. He combines strong skating, an accurate wrist shot, and a knack for protecting the puck from attackers. Comeau is very good making drives into the offensive zone with the puck on the end of his stick, looking for opportunities to pass or shoot. Plays a gritty game down low, and battles well along the boards and displays excellent spade work in the corners. Good work ethic and awareness on the ice allows for Comeau to play a good defensive game as well, which led to his being used on the penalty kill by Rockets head coach Marc Habscheid on a semi-regular basis. While Comeau is a strong offensive player, he seems to lack that extra gear that some other high-end players do, but even still, Comeau can contribute in many ways on the ice, not just on the scoresheet.
Comeau was dealt by the Calgary Flames to the Columbus Blue Jackets at the 2013 NHL trade deadline.
