Unrealistic expectations. He's been a game breaker in two games, both at the Verizone Center, and the team couldn't do anything with it. In the 1-0 loss, he literally played one of the best games of his career, and they still lost.
Basically, you're saying for the Rangers to compete with the Capitals, he has to go on a legendary Conn Smythe run. If they need Lundqvist to have one of the best post seasons a goaltender has ever had, than this team won't win a Cup.
I'm just being honest, I think it's stupid to call out the goaltender after a loss like that. There were dozens of reasons the team lost, and Lundqvist wasn't one of them.
He has consistently outplayed Holtby, but fails to win because the quality and quantity of chances come down at the Rangers end. He made three or four high quality saves in OT on top tier players in the NHL, and the Rangers still couldn't do anything with it.
Again, if you want Lundqvist to consistently win 1-0 or 2-1 games on the road, you're looking for something that isn't going to happen. He's not Hasek. And basically, you're looking for a Hasek caliber performance.
If you look at the kind of goaltending that recent Conn Smythe winning goaltenders have put in,
they were on substantially better teams who were able to take advantage of their goalie's performance and score timely goals. With the Rangers, Lundqvist makes the timely / big saves, and he has to make another timely / big save, and it continues to the point where one of them is bound to go in.
In the Game 2 loss the Rangers went 20 minutes without a shot between both the 3rd period and OT. In Game 5 the Rangers had 9 shots in 45 minutes. That's not a good team who is generating chances on the opposing goaltender. When that happens, all of the action is in your end, and it's eventually going to beat you (and that last goal Lundqvist didn't have a chance).
The Capitals are winning with Holtby providing adequate goaltending. And there is nothing legendary about it. And guess what? Their best player in Ovechkin hasn't been able to effectively beat Lundqvist. The Capitals team is better period. That's why they're on top, it has nothing to do with either goaltenders performance.
Lundqvist isn't Hasek. Once fans start realizing that, maybe they'll have more reasonable expectations.
