I don't know what I'd do with the lines because there are still so many different combinations I'd like to see...
Pastrnak - Krejci - Backes : Every time I see Pasta on the left wing he does something amazing, be it one timers off the rush, or 1on1 dangles for OT winners. He's played a lot of LW/off-wing in his career so it's no surprise he's comfortable there. Krejci the passer, Pasta the shooter, Backes the net front presence. That could be an amazing line. BUT who plays with 63/37? Can Spooner/Czarnik play 3C and not be minus players?
Marchand - Backes - Pastrnak : Marchand and Pasta are SO good together, but I feel like there isn't enough puck to go around for Bergeron to contribute. Backes on the other hand, doesn't need to handle the puck a ton to do what he does well, he can contribute by doing the heavy lifting in his own zone and then just setting screens in the offensive zone while 63/88 handle the puck and make plays. BUT they'll never put Bergeron or Krejci on the 3rd line or the wing for an extended stretch, they're too valuable in the middle and playing 19+.
Vatrano - Krejci - Backes : Shooter, Playermaker, Net Front Presence. I think this is how they wanted to start the season, and I think they wanted to keep Krejci/Backes together until that happened but they needed to mix things up to try to get some offense going. With Vatrano due back any day now it could be something they go to right away. BUT, can Bergeron contribute between 63/88? I feel like he doesn't get the puck enough when he plays with those two.
Spooner - Backes - Vatrano : Playmaker, Net Front Presence, Shooter. Same idea as the line above just different players. Could be a dynamic combination. BUT, where will the big, body presence come from in the top6 if this is the 3rd line? Maybe 63/37 can get by without one, but Krejci's done his best work with a big board presence in the mix.
Spooner - Backes - Czarnik : This is kind of a low rent version of the 63/42/88 idea. Lots of speed and skill on the wings with Backes doing the heavy lifting in the Dzone and in front of the net.
Schaller - Moore - Nash : I think both Schaller and Nash have done an admirable job stepping in for injuries and playing further up the lineup than expected but once they drop back to the 4th line they should dominate.
