He's a energy, agitating player with some skill and there's some upside there for sure. I don't think his game translates as well as Marlie forwards before him (Kapanen, Johnsson) but he was probably the 3rd best Marlie forward (even if it's a bit of a tier drop) after those 2 over the last few years.
Having seen him over the years, he's easily NHL caliber with upside. I'd be surprised if he's not a 4th line energy guy on a good team, at minimum, that can agitate, skate, and wreak some havoc on the forecheck and around the net. Good pickup for the Canucks.
I think the only problem with players like him is he's not exactly a play driver of any sort (those expectations would be lofty for any 3rd/4th liner) so if he's to do well, it's going to depend in part on his linemates as well.
