Projected by who?

Ok, not a Sabres fan I take it. No worries. Our top line (for better or worse) was skinner/thompson/tuch, probably keep those together. Cozens probably centers line two, mittelstadt line 3. Wingers in the mix for the 4 spots in the middle 6- olofsson, asplund, Krebs, Quinn, peterka. 4th line is probably girgensons between okposo and hinostroza.
On d, dahlin will play the right side, partnered with Samuelsson. Power will pair with either jokiharju or lybushkin, Bryson will likely be on the third pair with whoever isn't with power.
This is what it looks like for me anyways. There's always injuries, and lineups can be juggled frequently, sometimes several times a game.

yikes

not good

I'm leaning toward what you say, but I wouldn't find it shocking if OP has the right defense lineup.

The question comes down to whether you think Samuelsson is mature enough (probably) and has enough talent (unknown) to truly dominate on third pairing match-ups a la Sergachev over the last couple years in Tampa.

He looks like a pretty good complement to Dahlin on the top line and may be the solid partner that allows Rasmus to freelance in the o-zone. But Lyubushkin could play that role too.

Jokiharju is the question mark. He didn't really mesh with Dahlin, though they really tried hard to make that a thing. I don't know that it would be any better to pair him with Power. He needs a statement year to remain with the team after this season.

It's gonna be fun to watch 'em figure it out.

I don't get a vote, but for me-
Samuelsson-dahlin
Power-lybushkin
Bryson-jokiharju

My reasoning is that Samuelsson frees up dahlin to play his game, and I think we got a glimpse of what that looks like last year. Same idea with lybushkin and power. Both of our first overall picks would get a chance to excel with a physical defensive d watching the d zone. I don't think that jokiharju was the find that everybody (me included) thought. He seems like a middling two way d, not really excelling at much. It's too bad that Bryson is kinda the same thing, a solid defensive left d might be a better match for jokiharju. I would play the top 2 lines for the majority of the game and cross my fingers with bryson-jokiharju.
