Backes, 27, joins a list of Blues captains that includes Hall of Fame inductees Wayne Gretzky, Brett Hull, Bernie Federko, Al MacInnis and Scott Stevens. Originally drafted by the Blues in the second round (No. 62) in the 2003 Entry Draft, Backes has spent all five NHL seasons with the club, scoring 102 goals and compiling 218 points in 364 games, along with 500 penalty minutes.
