I don't have much confidence that we can win this series if we're missing all of Scandella, Leddy and Bortz. The left side of the D group was already our biggest roster hole and losing 66% of it is a massive hit. Defending in general is our biggest shortcoming as a team and losing two of our (at absolute worst) 4 best defending D men is a massive hit.
Scandella and Bortz are the team's two most frequent penalty killers. Without them, we are now down to 3 D men who can competently kill penalties at the NHL level (Faulk, Parayko, Mikkola). In the past 2 years, the Blues have gotten less than 40 combined PK minutes out of Krug, Rosen, Santini, and Perunovich. I don't like Leddy as a penalty killer, but he would at least be a better 4th option right now than any of those 4. I don't know the answer on the PK. PK minutes are too strenuous to make Parayko/Faulk both stay out the entire 2 minutes. I think you have to split them up because a pairing consisting of any 2 of Krug, Mikkola, Rosen, Santini, and Perunovich is a pure nightmare as a Blues fan. Even assuming we get a better showing from Mikkola, I can't come up with 2 PK units that make me confident. Our PK edge is gone and we are in survival mode.
Faulk, Parayko and Krug all need to shoulder a massive load.
If I were Berube, I'd get Faulk off the PP and tell Krug he's staying out all 2 minutes of every powerplay unless the Wild have several clears, force him to skate a ton and he needs Faulk to grab the last 20-30 seconds. We need Parayko and Faulk both playing 25+ minutes a night at even strength and on the PK. If we're going to win this series with only 3 legit NHL D men, PPs need to be used as a chance for Faulk and Parayko to rest and get ready to munch minutes. Krug used to frequently double up on both PP units in Boston. He's paid to be an elite PP QB and now is the time to deploy him like one so that Faulk/Parayko can try to keep Santini off the ice as much as possible at even strength.
We can maybe tread water without Scandella/Leddy/Bortz for a game or two. Luckily we have last change for the next 2 and can pair-match a bit more effectively. Engage in some extra post-whistle scrums in the offensive zone to increase the time between whistles and let Krug/Faulk/Parayko get an extra breath. We can win this series if it is just a game or two, but we are in big, big trouble if they are all out longer than that.
