All good news. Trying to work out the ideal Bruins defense for the final part of the season and the playoffs is no easy task. I'm still not completely sold on Chara-McAvoy but I suspect they stay together both because they'll be the two that Cassidy wants to eat up the most minutes and because Chara has quite a unique playing style and Chucky is the only guy who's really familiar with it. Krug-Carlo is probably also still a lock.
That leaves Gryz, Clify, Moore, Miller, Kampfer and Lauzon battling it out for the final 2 spots. My guess is that Moore gets traded, Miller will only be a reserve if he can indeed finally get back to full fitness, and Kampfer retains his 7th D status. So it probably comes back to Grzelyck-Clifton as the default 3rd pair, with Lauzon or Miller as an option to slot in against heavier opponents and Kampfer as the man to step in if a 7th or 8th guy is needed to cover injuries. Either way, we're once again in a very strong position on D, and while it hasn't played as well as you might hope over the last couple of months, I'd back them to raise their performance again when it really counts.
