IMO your vision of Newhook is off. He is either a 3rd line center or a 2nd line LW. His PPG is roughly a 50 points pace and he still has room to grow.

May I present Scott Laughton. We can accept Avs 2nd rounder.

Agreed. I think Newhook is on his way to being a solid 2nd line LW who can fill in at C as needed.
For next season i think Dvorak is a lock for 3C and Evans at 4C.
Offseason wish list would be a top 6 winger who can play with Dach and Newhook
a depth winger fin the bottom 6 - maybe Beauvillier at a home town discount. only 26 and showed some potential early in his career. Marty might be able to get him back on track.

Play Newhook and Dach together on the 2nd line. Neither is particularly strong in the faceoff dot so alternate them depending who’s strong side the faceoff is on. Also you’re forgetting Joshua Roy, guy will be playing middle 6 next season. So really the biggest need is a 2nd line winger, possibly a 3c but we already have Dvorak, Evans and Beck will be pushing for a spot next season.
