I really like these lines, although I really doubt that Ducharme would put Anderson on the 4th line. Plus the shutdown 3rd line is less useful in the regular season than it is in the playoffs.

The way I see it, Suzuki-Caufield are a duo, and Evans-Gallagher are a duo. Everyone else (Anderson, Toffoli, Drouin, and Hoffman) can get switched around in the top 9.

Yeah i doubt Anderson is on 4th line to start the year. If Drouin truly is back, I don't see why he wldn't play with Josh. So that leaves me to believe it will be Drouin-Evans-Anderson, Toffoli-Suzuki-Caufield, Hoffman-KK-Gallagher & Lehkonen-Paquette-Armia

I think to do the lines, you first have to look at duos that will be together like Suzuki-Caufield and do the obvious thing and have Lehkonen-Armia as 4th liners
I’d project
Toffoli-Suzuki-Caufield
Hoffman-Kotkaniemi-Anderson
Drouin-Evans-Gallagher
Lehkonen-Paquette/Poehling-Armia

Edmundson-Petry
Chiarot-Savard
Kulak-Romanov

With Paquette/Poehling, Perreault and Wideman as scratches

Suzuki and Caufield need a big body to create openings and opportunities. That's Anderson.

Kk, Drouin, and Hoffman all need sheltering. Put them together for the lion's share of offensive starts.

Put Evans with Gallagher and Toffoli for an all-purpose line, and give KK some shifts with them for more of an offensive tilt, since he doesn't kill penalties.

That leaves Lehkonen, Paquette(/Poehling), and Armia for a 4th line.

If Montreal does pick up another top 9 center, Evans (and KK if it's a better fit), can be bumped down a line.
