He fucking blows. He's a smaller Nik Grossmann (another slow guy who blocks shots and does nothing else), and this is likely setting up them giving him five years at 4 million per year with a full NTC. If not, it's a rental that doesn't help because he fucking blows. And they gave up a second round pick in 2015, a very deep draft.
They're the most out-of-touch organization in hockey and either don't understand or refuse to acknowledge advanced statistics. Deciding a guy is a good defender because he blocks a lot of shots is decades-old nonsense. He has the 9th worst Corsi in the league. He's awful.
