He has definitely shown more hustle defensively, and a much better stick than last year.
I still wouldn't call it amazing....but very encouraging. He's definitely on the right track.
The only thing that bothers me, is a lack of support at times. What I mean is, when he has the puck in a situation where he is being harassed at the blueline, I haven't seen any of his partners in preseason back him up at all (as in, start moving a bit - gliding - so they can either be open for a pass or able to put on the jets the other way and be ready to get any pucks poked out of the offensive zone and down to our end of the ice). Seems to be a recurring theme with the breakaways against us....the defenseman who loses the puck at the blueline is virtually the only one hustling back to try and stop a goal. The pairs aren't really supporting each other very well in that situation.
