I think you want Shaw playing above the 4th line. I'd also have Dach on line 3.

I think Shaw on the fourth line just allows the Hawks to roll all four lines all the time and I think the 3rd and 2nd line are interchangeable in this post. I just put Dach on the second line because Kane on the 3rd line looks weird lol

I don't think you put Dach with Kane. I think he's much better off getting to start in a smaller role. Look at what MTL did with Kotkaniemi last year.

My lines would look something like this:
Saad-Toews-Nylander
Debrincat-Strome-Kane
Kubalik-Dach-Shaw
Caggiula-Smith-Perlini/Kampf

I don't think you break up the Kane line if you don't have to.

Well my thought is that if Dach plays with Kane it will 1) help him grow as a player faster and 2) the Hawks will have 3 fantastic forward pairs between Toews/Saad, Kane/Dach, and Strome/Cat.
