Who are the 7 D and 10 F?
I count;
Forwards
----------
1.) Bergeron
2.) Marchand
3.) Backes
4.) Krejci
5.) Pastrnak
6.) Vatrano
7.) Nash
8.) Belesky
(I wouldn't bring back any of the rest. Waive or buy out Hayes. I wouldn't qualify Czarnik, Schaller. I wouldn't even qualify Spooner but we should be able to trade him, or hope Vegas takes him. If Belesky doesn't find his game soon, he could be a buy-out candidate as well )
Defense
---------
1.) Chara
2.) Carlo
3.) McQuaid
4.) Killer
5.) Chiller
6.) Krug
(that's it. You'd have to qualify Morrow to bring him back and I'm not so sure we do that)
Plus we will lose one of those guys to Vegas.
Whether YOU would bring them back is inconsequential.
Czarnik is likely to be qualified, as is Schaller. Morrow is 50/50 but might get qualified just to give LV another option to pick from. I'd take him over either of McQuaid or Kevan but that's also inconsequential.
Why buy out Hayes and the left-over cap hit for two seasons, when you can just bury him in the minors and eat it for one season with only the overage on the cap for 2017-18. Don't forget Seidenberg's cap hit rises by about a million for next season. How many buy-outs can they afford? You can be certain JJ despises paying guys to NOT play for the Bruins. I can't see him allowing a Belesky buy-out. And really why bother yet? It's not like Boston is in a position to go shopping on July 1st.
So that leaves:
Bergeron
Marchand
Pastrnak
Vatrano
Krejci
Backes
Belesky
Spooner
Nash
Schaller
Hayes
Czarnik
Chara
Carlo
Krug
Kevan
McQuaid
Colin
Morrow
I'll just go ahead an assume LV has zero interest in Subban or Khudobin. I'll also assume Schaller will hit the 70 games-played plateau (he needs 8 more games) to meet the exposure criteria.
Carlo, Vatrano, and Czarnik are exempt.
And you can be almost certain Boston will protect Bergeron, Marchand, Pastrnak, Krejci, Backes, Chara, and Krug.
Meaning LV will likely choose one of.
Spooner/Schaller/Nash/Hayes/Belesky/Colin/Kevan/Morrow/McQuaid. Obviously at least 2 of these F and 1 D will be protected.
Leaving Boston with either 11 F and 7 D, or 12 F and 6 D. Toss Hayes to the minors and your still at 10/7 or 11/6.
