Newhook would benefit some time with Suzuki and Caufield. He was heating up with them before his injury.
Right now, he doesn't have a lot of player playing with him that can push him upward. He's playing with 3rd 4th line caliber player and with a younger player than him and mostly against the other team second line every game. Which make it really hard for him.
Good news is the most gametime he will have against that kind of competition, the more he should progress and that progress will probably translate when real good players are added with him.
