Kalinin is a good player but he's not a player I would spend a lot of money on because he's not going to add anything to our defense that we really don't have already in place. Namely he's not going to run the powerplay and he's not going to provide an intimidating physical presence.
As for Malik--there is a lot of anger directed at him right now. FWIW I think all of our impending UFA's on defense--Roszival, Malik, Mara are this season playing for next years contract. What they do on the ice this season should have bearing on that. Five games in is not enough after two full seasons to decide on Marek. I'm not a big fan of his but the state of the system and our current defense prospects, the availability of other free agents, cap room are also all going to be factors. It's not smart to cut ties when you don't need to. We don't need to now.
