No reason to put the Tkachuk's together on one line, they bring similar things to the table and I don't think they have some sort of fantastic chemistry together either. I would imagine Keller would be the LW with Matthews and Matthew or possibly Jack Hughes if the former doesn't crack the main roster.

I think Eichel or Hughes would be the 2C before Thompson. Maybe Hughes would be put on the wing, on the 2nd line but I think it's more than likely that Thompson goes to the wing. The two Jacks probably are the second line, with Hughes on the wing or Hughes 2C and Eichel 3C.

I think your defense is a bit too young, if Werenski is a top defenseman still he's probably drawing in for sure. I would guess that only one of L Hughes, Sanderson, and Faber get the nod or two of the previous 3 + Miller.

Making the lines might be even harder than making the roster .

Age wise I’m trying to think 2 years from now so I’m not sure if ZW is still good then.

He'll be 28 turning 29 though age-wise, but who knows, to be fair there's a good chance that he's injured.
