As usual, center Dave Bolland might just be the key to everything.

When star forward Patrick Sharp was in the lineup, it was Bolland's erratic and unproductive first half that led to concerns about the Blackhawks' lack of offensive depth up front.

With Sharp out with a fractured wrist, it's clear the onus is on Bolland to raise his game. Coach Joel Quenneville kept him on the second line with winger Marian Hossa

after using him most of the season to handle checking assignments.
