This comes down to a difference of opinion on Lucic.
I think Lucic will want $6.5-$7M in a long-term deal. I think he deserves that 25% of the time, and half of it the other 75% of the time. I wanted no part of paying him anything over $6M for anything more than 4 years. If you feel differently about him, and it's clear you do, we obviously can't discuss the merits of this trade.
All in all, I think they got very good value for him AND they dodged the bullet that was going to be his next contract. It's a clear win for me. As for the team now, they are clearly worse. However, if the goal was to free up money, dodge long-term potential killer contracts, they are on their way.
The key to this deal, and the Hamilton one, is what they do next. Will they make another major move or two to fix this defense and add some goals up front? We shall see.
I would actually say that it comes down to far more then a difference of opinion on Lucic's value honestly. I think it comes down to a fundamental difference of opinion on the long term strategy of building a dynasty.
"Wait and see what happens next before judging this deal" has essentially been the company line since the Joe Thornton trade, and it has been used to gloss over the fact that Boston time in and time out trades players at their lowest value and gets back multiple mediocre pieces in return that never come close to making the same impact.
We saw it with the Thornton deal, a generally accepted horrible return but one many Boston fans feel the need to justify because 7 years later Boston won the cup, as if trading Joe Thornton was the sole reason they were able to win it and they wouldn't have been able to win otherwise. Which of course conveniently ignores the fact that quite literally the entire roster outside of Patrice Bergeron was changed out and the front office staff had to be almost completely replaced. They decided to move him after a very questionable playoffs and after a long lockout (and then there was something about a broken fax machine or two) when his value couldn't have been lower.
We saw it with the Kessel deal which immediately made the Bruins a worse team. They waited until they were under the pressure of an offer sheet to get a rather controversial deal done involving only draft picks for what had been the most promising goal scorer Boston had seen since prime Glen Murray. Kessel went on to put up five 30+ goal seasons in Toronto. Luckily the draft picks worked out, but then...
We saw it with the Seguin deal. Trading him when again when his value was lowest after a rather offensively ineffective post season. At least with the Seguin deal Boston got back pieces that could be considered added depth, but there shouldn't have been any confusion as to who got the better player (there were, and there no doubt still is but there shouldn't be).
And now we've seen it again with both the Hamilton and Lucic trade. Say what you will about Lucic's contract or whether or not he'd be worth his future earnings that he hasn't yet committed to, he is an incredibly unique player and Boston traded him at the worst possible time. Cents on the dollar. The typical justification is being rolled out already (didn't gel with teammates, wasn't a good fit, sense of entitlement) and the typical optimistic fan base line that consistently goes hand in hand with it, "hey at least we added depth!". In order to have depth, you need to first have a solid roster. Otherwise you just have a hockey team chalk full of mediocrity no matter what kind of Boston spin is put on it.
