The Chicago Blackhawks (31-21-7) are back at the United Center today for an afternoon tilt with the St. Louis Blues (36-15-7).

After a 6-1 win over the Columbus Blue Jackets, is the Blackhawks' offense all tapped out?

It may very well be the case. 

The Blues have a very impenetrable blue line with Brian Elliott (19-5-2) having the season of his career in the crease since being with the Ottawa Senators.

The Blackhawks will need to crash the net early and often to attempt a couple of soft goals. Meanwhile, we should expect to see coach Joel Quenneville ride Corey Crawford (19-14-5) while he's hot.

Here's the special teams breakdowns:

Blackhawks power-play: 16.7 percent (18th); penalty kill: 78.8 percent (26th).

Blues power-play: 15.2 percent (25th); penalty kill: 81.4 percent (20th).

Injury updates:

Blackhawks: Niklas Hjalmarsson (IR) with concussion-like symptoms; Steve Montrado (IR) with an upper-body injury; and Daniel Carcillo (IR) left knee surgery.

Blues: Carlo Colaiacovo (IR) is out with a sprained right wrist; goalie Jaroslav Halak (IR) out with flu-like symptoms missed the game; Matt D'Agostini (IR) with a head injury; and Alexander Steen (IR) is out with concussion-like symptoms.

The edge: 

The Blues are 10 points higher in the standings right now with 79, and have been way more consistent recently. The Blackahwks are looking poised with two points. Today's game will be the tall-all sign on whether or not coach Quenneville actually has implemented some significant changes that has led to the success of the Blackhawks.

Quick fact:

Blues coach Ken Hitchcock holds an impressive 30-8-7, the best win percentage among coaches this season.
