While that's true, and I've great doubts about whether this team will make it (despite the huge wealth of talent), look around the playoffs right now. The Hawks and Blues are, at least, on par despite the Blues having had no ultimate playoff success, like the Caps, and them playing the defending champions supposedly loaded up with elite talent. Anaheim - one of the SCF favourites lately - took a long time to wake up against Nashville of all teams; the Rangers struggled against a team icing its third-string goaltender for most of the games - only Tampa Bay have really easily succeeded, and I thought the red wings put up a strong challenge at points.
This teams problem isn't the Flyers - it's not even Neuvrith. It's the Caps themselves - can they adapt their game as their opponent adapts to the Caps?
People quoting possession statistics, shots on goal, shot attempts etc. Do have to remember that you still need to be smart every element of your game, and at a certain level these are distinct components of play where one bad strategy (like where you aim your shots, or where you're taking shots from) can render the rest irrelevant. We need to not win games by fluke, or only by capitalising on mistakes: we need to play a game that actually beats the opposition at our pace and at our doing. That's where the Caps are struggling right now - and only strategic changes (however small) will fix this. Or, you know, fluke goals or a Neuvrith brain freeze. But that doesn't win cups.
