I think the Penguins are as vulnerable as they've been in years. Today was their 303rd game in the last 36 months, Malkin and Hagelin are both beat up, Hornqvist was beat up in the Flyers series, Murray has been inconsistent this postseason and the Caps have outplayed the Penguins for 100+/120 minutes in this series so far. There will come a point in this series when the Penguins will hit a wall from having played that many games in that span. Even if Malkin comes back for game 3, or at some point in the series, he's fragile at this point.
