The big news out of the Chicago Blackhawks this past week was the announcement that starting goaltender Corey Crawford has been placed on injured reserve, and that there is currently no timeline for his return to the lineup.

If he has to miss an extended period of time it could be a damaging blow to a team at a position where it really can not afford one. If there is one player this Blackhawks team can least afford to lose, Crawford is probably the one.

Prior to his injury Crawford had been having an outstanding season for the Blackhawks and owned a .930 save percentage that is fifth best in the league. That performance has been huge for a Blackhawks team that has its share of flaws, especially when it comes to its defense.

The Blackhawks are allowing 34 shots on goal per game this season, the third highest total in the league and it continues a trend from recent seasons that has seen the team go from being one of the absolute best shot suppression teams in the league to one of the absolute worst. Typically, that has not been a great recipe for success in the NHL. The Pittsburgh Penguins showed last season that it is possible to win giving up that sort of shot volume, but onlly if a team has scoring depth and great goaltending to cover it up.

With Crawford in net the Blackhawks have been getting great goaltending. That has allowed them to stay in the top-five in goals against despite bleeding shots and shot attempts against.
