The Canucks aren't out of it so more than likely their going to want Zacha/Coyle as part of the return, plus a prospect (Lysell/merk) and a top 6 defenseman (Carlo) I think in the end you have to ask does it put the Bruins in the playoffs and deep. No certainity there.
That is a key question.
I don't know if that return gets it done - if it's Zacha + Carlo + Lysell, maybe? - but I do think you have a two-nickels-for-a-dime situation there. [The rumored ask from the Rangers sounds like a much stronger package to me.] Miller is the best player in your Boston deal, clearly, and therefore I'd probably do that even if it leaves the Bruins scrambling to fill some new holes. Maybe it takes into next season to really make the most of having Miller but still... they need to find some real talent unless a rebuild is coming.
This is not unlike the Horvat trade to NYI. A few years later, who is better off from that trade? Horvat is a key player for the Islanders (though still an admittedly flimsy team) while I'm not sure if Vancouver benefited much at all; so you trade several pieces but it's all good in the end. Question is, would Miller become like Horvat also in that he joins a team that is slowly sinking even if he's a good add in a vacuum? BTW, how is Vancouver going to be successful if they keep shipping out top forwards who are also leaders? Horvat, Lindholm, maybe next Miller, etc. That's tough to absorb.
Age is a question as others have said. Miller turns 32 this year. Are the Bruins going to pull off a Caps like turnaround in 12 months? Or are they facing an extended tailing off and rebuild process? If it's the former, Miller could help (if he's a good citizen in Boston). If it's the latter, he alone can't stave that off and he'll be miserable.
Since Boston and Vancouver seem to be enjoying swapping numerous players (last summer esp.), why not keep it going...
The 1,000,000 question is, should the Bruins even entertain such a move? I just think the Bruins are too inconsistent this season to consider a trade like this.
You may be right there.
Question is, even if that's the case, can the Bruins right the ship enough next season to make it worth having Miller?
With pieces like McAvoy, Pastrnak, Swayman in place, and some good players beyond them (if not enough overall depth of course), it could be premature to write off the Bruins chances to turn things around next year.
Miller does bring an intensity this team could really use.
