I came away less than impressed but that's probably because of the caliber of player we have at the moment and it was just the first practice.
The only one who sparked was Atkinson. Dubinsky, Foligno, Umberger, Johansen, and Anisimov didn't exactly look like world beaters. Our defense looked like they were ready to go, though which is good.
Mason looked better than Bobrovsky. That's less a positive about Mason and more a negative about Bobrovsky. I too noticed that Bobrovsky looked smaller than 6'2". He was playing pretty far back in his crease.
Granted it was only a few hours and they weren't going full out. We'll have to see. I did like what I saw from Brassard. He was good along the boards, his passes were crisp, and he was hustling. Gillies also looked good (better than Boll and Dorsett IMO).
A lot of guys came away surprised by the pace of the practice. Hopefully by this time next year they will be so used to working hard that it'll be "business as usual."
