​If you ask any hockey player, they will tell you games are won from the back out, which means good teams must think defense before offense. A solid defense can only succeed with a good goalie and, for the ​Boston Bruins, they have a good one in Tuukka Rask.

Rask was pivotal in Game 4, stopping 39 of 40 shots, backing Boston to a 4-1 win, which evened the series up at two games apiece. The netminder was dialed in, knowing that a loss in would have moved his squad to the brink of elimination. 

Rask's biggest save came on a penalty shot by Boone Jenner in the first period, but he faced a plethora of shots from high-scoring areas later in the game, stopping all but one off the stick of ​Artemi Panarin.

The Bruins' pace started to decrease after they went up 2-0 early, but the play of Rask deterred any hope Columbus had from coming back in the game.

Plenty of the goaltending conversation in this series has been about Sergei Bobrovsky, who has been brilliant for the Blue Jackets on their current run. But last night, Rask showed that he is a phenomenal goaltender as well, and he has all the ability in the world to steal games for his team. 

This series should go the distance, and if it comes down to a win-or-go-home Game 7, this version of Rask will need to show up for the Bruins to have any hope of moving on to the Conference Finals.
