Hard to predict of course which makes it fun 
Pros and cons to many different possibilities but I’ll say I’d like to see:
Hyman-Matthews-Marner
Thornton-JT-Nylander
Robertson-Kerfoot-Mikheyev
Vesey-Spezza-Boyd
I’m thinking the 2nd and 3rd line both need to get going a bit more at even strength, so perhaps above can shake things up a bit.
Less popular might be that I wouldn’t mind seeing the following, only because Hyman seems to make any line he’s part off awesome:
Thornton-Matthews-Marner
Robertson-JT-Nylander
Hyman-Kerfoot-Mikheyev
Vesey-Spezza-Boyd
Feel like we could have 3 very strong lines there. Thornton was starting to develop chemistry with Mitch and Matthews before the injury but really to me the biggest gain is that 3rd line. I also like the idea of Robertson with Willy and JT but he may not be ready yet.
