I voted for Granlund. During that early season stretch where no one on the team could score except for him, he and Dubnyk really carried the team. Granlund was pretty consistent all season, and even when he went cold in March he was still putting up the occasional point. Other guys on this team that go cold look like they'll never score again (or make a save again, as is the case with the goalies). Basically, his high was the highest of anyone on the team, and his low was still higher than anyone else's low.
I also did not realize until his rest game that ruined his GP streak that he never misses a game. Not bad for a guy that was called too slow and small.
