First of all, this expansion draft protection is something management was of course fully aware of when they signed him, it's part of the plan.
I agree that Zuccarello should shoot more, and he has a very good shot. But he has a tendency to make things more complicated than they have to be, because of his desire to help his linemates score. No doubt.
But I would disagree if you say he doesn't fit. Right now he has a mentor role for Galchenyuk, who's playing better and better. Gally could turn into a decent center.
Zuccarello himself has taken a more passive role on the ice because of his injury, playing 12-13 mins a game. This is in agreement with the coaching- and medical staff. He's saving himself for the playoffs (if they make it). Zuccarello has a great playoff history, and he was on fire last year for the Stars.
