Personally I'm happy we traded him, with us at least, he wasn't able to elevate his game in the playoffs. 4 assists in 17 playoff games, 2 of which (maybe 3?) were empty netters.
With that said overall he's a pretty decent player. He's got good size and speed. He's not very physical, but he's also not out there getting ran over or giving it away to avoid checks. He's got a very hard and accurate wrist shot from the slot, but has trouble finding open space, which is even harder in the playoffs. He's versatile as he can play LW or C, he can PK and he can be on your PP if need be. Defensively he's pretty responsible, I mean he's no Bergeron or anything, but he's trust worthy. Basically he's a well balanced player.
To islanders fans, I hope he does well for you. He definitely will give the effort game in game out.
