Domi with Nylander is interesting. I would have personally put Domi with Matthews given how well it worked, Marner with Tavares and built a line around Nylander as well. But, I'm not a NHL coach, just an armchair GM.
So what's this going to look like?
Knies Matthews Marner
McMann/Jarnkrok Nylander Domi
McMann/Patches Tavares Robertson/Cowan
Patches Kampf Holmberg
Even with Dewar out... it seems like we have just too many bodies. Someone is likely to be claimed off of waivers, or traded. Then add in Grebenkin, as someone who could steal a spot. It's going to be an interesting camp and preseason.
