You have to think Gonchar will require a practice or two before he plays, but you never know. Boston is coming off a back-to-back on Thursday and might be ripe for the taking. Having Gonchar on the 3rd pairing and PP might be a smart idea, but I don't think it should be at the expense of Beaulieu as I feel he's necessary for the 2nd wave PP duties and has been playing pretty well.
I'd probably take out Weaver who has been struggling to find his form from the post season but has been getting better over the past few games.
Markov-Subban
Beaulieu-Gilbert
Emelin-Gonchar
I do kind of worry that Therrien might be inclined to put Gonchar with Markov however, which would be a bad idea with how much Markov plays. I think the pairings I posted might be the best place to start. Gives Emelin someone who speaks Russian, and Gonchar less responsibility to start his Hab stint.
Thoughts?
ps. Side note, because this is a Tinordi thread I don't think he should have been sent down but I get them not wanting to have 8 defensemen on the active roster so he's probably the only choice at this time. Injuries do happen though so I can't imagine he'll be down for long if he has a good attitude and puts in the work.
