I think the lines probably start the years as:

53 - 72 - 89 (Top line remains unchanged now that Tage is not hurt)
77 - 24 - 71/22 (Keep the kids together when they can. I think Cozens' defense can carry Olofsson's lack of defense the best. Olofsson traded as soon as Quinn is back)
19 - 37 - 12/13 (Give Krebs the chance to move up and Mittelstadt the chance to have some weapons on his wings)
28 - 17 - 22 (Solid defensive fourth line. I think they load manage Okposo at times and Rousek slides in here)

23 - 26 (Top 16 defensive pair)
25 - Clifton (OP gets a solid defensive partner)
10/61 - Johnson/46 (Mix this line up when they need to based on matchups. I think Johnson might get some load management like Okposo so Stillman/Boosh will work in)

I will let granato decide how to make up the forward lines, and your guess is as good as any.
Buffalo finally balanced their LHD with RHD as a result the Sabres may try to pair RHD with LHD.
With that in mind, Clifton turned down at least 10 other teams and one with higher AVV and longer term.
He also filled in for McAvoy and played top pairing with Lindholm for the first couple of months of the season.
Reading between the lines, the defense easily could be:
26-Clifton as mentioned above solid defenseman had only 4 fewer hits than Dahlin and Samuelson combined.
25-6 Johnson could be the vet mentor for Dylan
23-10

BTW my guess is they are done for now, maybe at the TDL they will be sellers.

Do you mean buyers at the deadline? I think they have a reasonable shot of making the playoffs.

Sellers to make room for Kulich, Savoie, Benson, Johnson.
There were 12 first round picks traded near or on the TDL.
Two teams missed the playoffs, 5 teams were bounced in the first round, 4 teams in the second round (Boston traded two first round picks therefore only 11 teams).
Vegas made modest moves and traded prospects and a couple of picks, 3rd and 7th.
Florida essentially did nothing.
If Olofsson has close to 20 goals, Mittelstadt has nearly 40 pts and Lyubushkin is playing well they would all have value to teams looking to add offense or a RHD.
I am not trading the above players because they are bad, but rather they are good and Buffalo should receive great returns.
They are traded also to bring in two or three players on their ELC so Buffalo has cap space (trading those three and replacing them with ELC will add nearly $7,000,000 of space) to sign current members of the Sabres.

Over the past 7 years Buffalo has drafted really well, they should continue to collect first round picks to continue the making of a dynasty.
