For the most part, I disagree...but it's difficult and nuanced. That's why I brought up the Chiarelli thread earlier.
12 forward, 6 D, 1 goalie wise I don't think Sweeney has done anything at all to make the roster better than the one that
@BruinDust posted. A large portion of it is the same, which...that's a decision by Sweeney to keep those guys and credit to him for that I guess(even though in some cases he's needed to be saved from himself..like wanting Martin Jones over Tuukka Rask).
I really struggle to say any roster transaction and especially the collective group of transactions has lead to a 20 point swing in the standings and missing playoffs to cup finalist.
I think even the most avid Sweeney defenders know this little window has been driven by an incredibly abnormal resurgence of the core, which looked just about down and out a couple of years ago. If I told you 5 years ago that Bergeron, Krejci, and Rask were all going to be having career years in their mid-30s, Chara would still be collecting Norris consideration and all star votes in his 40s, and Brad Marchand was going to jump from a 42 point player to a 100 point player at the age of 30 you would have looked at me as if I had 3 heads if not more.
So I know I've mentioned this in the past and hate to beat a dead horse, but I'm very specific when I say roster transactions because we all saw the night and day difference from the second Bruce Cassidy took over behind the bench and Sweeney was the one who made that change(even if he did it in a completely cowardly way by waiting until the middle of the Patriots SB parade to do so). Overnight they became a different team. Sweeney definitely deserves credit for identifying a problem in the locker room and not only acting on it, but filling that hole with someone who was able to drive much much better results from the same level of talent..
