While I agree in principle on it being a "weird add" from a roster building approach - if the Hawks were able to O/S Bourque for a 2nd, and he did turn into the 25-30g/25-30a type of middle six winger - he'd EASILY have much higher market value and could be moved when the next wave of prospects is ready. Bourque would also be further along and more likely to contribute immediately. Top 9 would be some combo of Bedard, Frondell, Nazar, Bertuzzi, Lardis, Kantersov, Moore, Greene, Borque. (Assume 4OA is a d-man or not in the NHL this year - if you get Stenberg then this is a moot point.)
I look at it like if they got Bourque - they're buying out or burying Bura or Manga to open up a space for him. Agree that's it's trying to hit a single instead of a homerun, but if JR doesn't work it's an option.
