What they should do:
1) Split up GCR. Put Rakell there
2) Promote Blueger to 3c and stop using Carter in any kind of shutdown role. Give him soft minutes and manage those minutes. He can produce some offense if given some soft minutes
3) Demote Rust off of PP1 and try Rakell there. If that doesn't work, take Rakell off of p1 and run a 2d PP1 with Petry and Letang on it, and Malkin/Sid/Jake down low.
4) Get Kapanen back into the lineup. Yes he has sucked. Yes he's deserved to be scratched. But he can skate, and this team needs to get its speed game going. They need to get him going somehow.
5) Stop playing Jarry until he's healthy. If he is healthy, then ride him until he plays his way through his struggles. Desmith has been fine and all, but Jarry is the guy. They will not go on some extended run with Desmith in net.
Guentzel-Crosby-Rakell
Zucker-Malkin-Rust
McGinn-Blueger-Heinen (use this line in a shutdown role)
Archibald(or Poehling)-Carter-Kapanen (give this line soft minutes and see if they can chip in a little offense)
d pairings how Sully have been doing them have been fine. When POJ is healthy though, get him back with Letang and get MP back with Petry. Move Dumo back to the third pair.
Ride Jarry
That's how I would draw it all up. If you're asking me for actual solutions rather than doom and glooming about how this roster looks, this is how I would do things. Would it be enough? Who knows. Dont know if Sully will ever try my ideas.
