Don't you guys think that Vatanen might have a down year because of the offseason surgery and the fact that he most possibly missed a good portion of the summer training? I bet that the Devils knew that and they are thinking this trade in long term, not just this year.
Shoulder surgery is absolutely a factor. However, you're kind of ignoring that he was pretty bad for most of last year too. He's not been the same player since Bruce left. Maybe it's the system, maybe it's because he's playing in the top 4 now, and not on the bottom pair with Stoner, who knows. Supposedly he didn't take his off ice training seriously the offseason before this past one. I just know that he's been on somewhat of a decline the last 2 years. I think he'll be better next year though when his shoulder heals fully. Probably will be a better fit in NJ's system than Carlyle's too.
