You can never have too many defensemen, especially if you're the Blues. Sure, they have their top six, and sure, they have a seven and eight guy in Ian Cole and Kris Russell, but what if there's a rash of injuries? God knows it's happened before.
Taylor Chorney was the plug-in guy briefly a few years ago when defensemen were dropping like flies. Last season, the Blues signed him as insurance and as a way to bolster the blue-line in Peoria. This year, Chorney will be bolstering the blue-line in Chicago (in theory, if they feel the need to let him play). The Blues have re-signed him to a one year, two way deal. Chorney is getting a little bit of a payraise; he'll be getting $600,000 at the NHL level and $175,000 at the AHL level according to CapGeek.com.
Chorney has played in 61 NHL games in his career, and he'll have to fight to play in more this season as well.
