Needs context. I care less about his stats, more about his skill set. He’s already proven what he can do in the right situation. He didn’t fit their system, fits ours perfectly. He’s also still coming back from a pretty major injury.
The right situation for Vatanen was under Boudreau, with relatively sheltered minutes. He wasn’t really a bottom pairing guy, but he wasn’t a top 4 guy either. Boudreau liked to roll the D lines, and as a result Vatanen was never really “just” a third pairing guy, but he wasn’t seeing the legit top 4 match ups either.
Even under Boudreau, when Vatanen’s responsibilities increased, his play started to fall off. This was especially true offensively, where he needed to be(and was) more responsible defensively, but at the expense of taking risks offensively. Vatanen has never really been able to find that line where he is a stable influence defensively, but a factor offensively, at even strength. That isn’t a system issue. It was there with Boudreau as well.
Offensively, Vatanen is at his best(at even strength) with less D responsibilities. You might think “well, duh, that’s true of all offensive D” but it’s very prevalent with him. He has struggled to be a top 4 guy, in overall responsibility, while still being able to produce the kind of numbers his career stats indicate. The context of those numbers is that they exist, at least in part, because he had two D pairings ahead of him seeing a lot of D responsibility, while he was being tossed onto the ice in a lot of more favorable situations.
In other words, like Henrique(it sounds like), he has his issues. He should always be pretty good on the PP(albeit inconsistent, because sometimes he just won’t shoot, or he overshoots), and he will be good on the PK, but there are two Vatanens that exist at even strength: the capable puck mover who is solid all-around as a top 4 defenseman, or the dynamic offensive defenseman who needs to be managed defensively. There have been a couple of times where those two defensemen came together, and he looked damn good, but he always seems to fall on one side of the line or the other. It would be really cool to see him figure that part out. He’s a good player regardless, but that would make him a great one.
