Sometimes the goaltender is changed because he isn’t playing very well. Other times, it’s because the team playing in front of the goaltender needs to wake up.

Whether or not coach Joel Quenneville made the switch for the first reason we don’t know quite yet. But it definitely got the Blackhawks’ attention and the desired response.

Scott Darling was stellar in relief of Corey Crawford, stopping 42 shots, and Duncan Keith scored the winner 7:49 into in double overtime as the Blackhawks came back to beat the Nashville Predators, 4-3, in Game 1 of their first-round series on Wednesday night. The Blackhawks scored three goals in the second period, via Niklas Hjalmarsson, Patrick Sharp and Jonathan Toews, to erase a 3-0 deficit en route to the victory. The two teams play Game 2 here on Friday night.

It was a masterful performance for Darling that has to have Quenneville seriously considering starting him in Game 2.
