According to the Peoria Journal Star, Wagner is an offensive defenseman. He is 25 and has played 46 games in the NHL over four seasons. He was an undrafted free agent who surprisingly made the Blues roster in 2007. According to stltoday.com, Wagner has struggled to regain his form after being sent down to Peoria and breaking his leg in 2008. Hopefully a change of scenery can help him, because he seems to have the offensive skills to play in the NHL.
Wagner is a UFA after this season.
Guenin is 26 and definitely a stay-at-home kind of guy on the blue line. He's also a UFA after this season.
