Coburn was the 2001-02 WHL rookie of the year, won a gold medal at the World U-18 Championships and was invited to Team Canada’s Final Evaluation Camp for 2003 World Junior Championships. Played in the 2004 and 2005 WJCs.
Coburn was chosen in the first round, 8th overall, of the 2003 NHL Draft by the Atlanta Thrashers.
Coburn joined the AHL Chicago Wolves in March 2005 after his junior season was over.
2005-06: In his nine games with Atlanta to start the year, Coburn averaged just 7:43 in ice time, posting one assist. The writing that he was not yet ready was on the wall when he played only 1:53 on Oct. 22 after being on the ice for the first goal against. He took just three shifts all game.
Having been told to find a place to live in Atlanta, he was sent to Chicago on Oct. 26 and lived in a hotel for an extended period. The 21-year-old would not return to the team all season, as the only call-up on defense was Popovic. In Chicago, Coburn had six goals and 20 assists in 73 games and was a +12, tied for second among defensemen. The 6’5 blueliner had 136 penalty minutes.
2006-07: Coburn was acquired by the Flyers at the trade deadline for veteran defenseman Alexei Zhitnik. The 6’5, 220-pounder had been unable to crack the Thrashers’ top six defensive rotation early last season. He split time between leagues, appearing in 29 games for the NHL team due to injuries (in which he registered four assists) and in 15 games with the Chicago Wolves of the AHL (one goal, 10 assists).
Coburn became an instant contributor for the Flyers, and while he has made his share of mistakes playing for one of the NHL’s youngest teams down the stretch run, he also displayed flashes of brilliance. He notched seven points (three goals, four assists) and 16 PIMs in 20 games with the Flyers, while playing significant minutes in all game situations.
Coburn is a mostly stay at home defenseman who skates very well and makes a good outlet pass. Though not a bruiser, he uses his size to his advantage.
Coburn was dealt by the Philadelphia Flyers to the Tampa Bay Lightning in exchange for Radko Gudas and first and third round picks.
