Here are a couple of good reasons why:
1. Murray hasn’t exactly fallen apart. He only allowed three goals in Saturday’s loss. He was excellent in the three games before that, and he has a .937 save percentage in the playoffs.
2. Marc-Andre Fleury hasn’t played since March 31. Even if there was legitimate concern about Murray, it would be a heck of a risk to throw Fleury in there at this point.
Now, if Murray struggles in Game 6 and the Capitals force a Game 7, perhaps the argument for a change could be made. Though even then, the risk of playing Fleury would remain.
But that’s a decision for another day. So far, Murray has not deserved to lose the net. Without him, the Penguins could easily be behind in this series. Instead, they’re in the driver’s seat, with a chance to close out the Caps tomorrow at home.
