Lundqvist is playing that good.
The Caps are getting their chances every game, but Lundqvist is just playing at the top of his game right now. Last night he showed yet again why he has been a repeat Vezina finalist, making some clutch saves when the Rangers needed it most.
You also have to tip your hat to the Rangers defense as well. Aside from their slip-up in Game 3, the defense has been amazing. Not only blocking shots, but clearing rebound opportunities, and forcing the Capitals (for the most part) to the outside shooting lanes, instead of coming through the middle and getting too close for comfort.
But without Lundqvist in net, this would be a totally different series.
