I have to say that overall I'm happy with Sweeney to this point.
That's not to say I agree with everything. I would have taken a different route, namely by cutting down on the veterans on the pro roster a little bit more around the time of the Lucic deal, and then signing some free agents to fill the gap, eventually moving them out to pick up more young pieces, but the GM, as Machiavelli said, has to deal with the matter at hand, no GM exists in a vacuum and part of his job is satisfying his bosses who want playoffs. It is what it is. Plus there is no guarantee that the Bruins would have had a successful rebuild if they had blown it up.
So the positive elements to me of Sweeney's approach are that the young players coming up aren't placed in a toxic environment, there are good veteran leaders around, the team wins its fair share, and the youngsters don't have the world on their shoulders to be saviors.
I realize part of the angst is that the Bruins are in the mediocrity zone which is what I would have hoped to avoid by cutting down faster and subsequently building up faster. It is understandably frustrating because you don't get the carrot of high draft pick nor the idea that they could soon be a contender.
That said, I do think that this team if it got hot at the right time, and if they added a Top 4 defenseman and another solid winger, could possibly win 2 playoff series. But I wouldn't consider them a true contender due to the higher ages of key players and inexperience in younger ones. Sooner or later they would get exposed, likely sooner, and consequently I am not in favor of rentals.
The good thing is that we're in the hunt for the playoffs and I'm choosing to put my attention on that. I'm excited to see if we can take the last division spot. I find the team likable because I think they generally give a pretty good effort.
I think the future of the defense is looking pretty good, but that is going to be at another 2-3 years to see the fruit of labor. My objective for Sweeney is to look toward picking up a young center with high upside. I don't mean guys that "could one day play in the NHL". I mean a young center that you can build around. Of course, #1 pick franchise centers don't grow on trees, but if Sweeney turns up a stud young center, via trade, draft, or development of the guys already in the org., then I think this team will be in good position
