The only guy the bruins should have interest in there is Bjugstad.

The ask for Gavrikov is pretty well publicized at this point- a 1st and a 3rd, like what we got for Savard or Foligno. Retention included free of charge.

Gavrikov: This year's 1st feels like the starting point to me but the Bruins would have to add more to that, especially since their pick looks to be like 27OA at worst.
Toews: No idea honestly, wouldn't trade for him personally.
Bjugstad: 3rd or 4th rounder
Labanc: No idea, shouldn't be too much though.
O'Reilly: 2 2nds maybe, not sure on his value at all though.
Garland: A 2nd+ or something like that.

Truth ^

Recent article states labanc is likely a player for player trade, maybe labanc for Rielly?
