Honestly, with the forwards, I'm not sure what the best lineup is.
We know that Marchand & Bergeron and DeBrusk & Krejci will be paired together, and that Coyle will be the 3rd line C. That leaves 4 spots, three of which will be filled by Pastrnak, Johansson, and Heinen. I think the key is figuring out two things first. Where does Johansson fit and who does Coyle play the best with?
Pastrnak is either 1st or 2nd line RW. Heinen is either 1st line RW or 3rd line LW. Johansson is either 2nd line RW or 3rd line LW.
I think the two options are:
Marchand-Bergeron-Pastrnak
DeBrusk-Krejci-Johansson
Heinen-Coyle-Wagner/Backes
Nordstrom-Acciari-Backes/Wagner
or
Marchand-Bergeron-Heinen
DeBrusk-Krejci-Pastrnak
Johansson-Coyle-Wagner/Backes
Nordstrom-Acciari-Backes/Wagner
If I'm being honest, I'd like to find a place for Kuhlman, but I don't expect it unless there's another injury. (knocks on wood)
