While we certainly have issues and adjustments to make, (as dlpin has said so eloquently - TP), I just don't see all the gloom-and-doom and signs of bad karma that seem to be running amok on the threads these days. KG is not remotely 100%, and I didn't expect him to be at this point.
The chemistry is not what it has been or should be, but why would anyone expect that after the injuries and absences? The defensive concentration has been compromised as well, but again, I don't expect perfection in that department with Ticket having been out so long.
I think we're a bit spoiled here in Boston and we take for granted that we're still, despite all the problems, one of the best teams in the NBA. Every year we go through similar periods, as we did even in our championship year, and I just don't see this as being any more or less impactful as those, or any more troubling.
We need to take a small step backward, take a deep breath, and remember who the players are on this team, who the coaching staff is, and trust that they have the knowledge and experience and desire to make the necessary adjustments required to get back on top.
If this were a week before the playoffs I might feel a bit differently, for timing purposes only, but it's not, and while these losses are always hard to take, most of the other teams in the NBA would be more than happy to trade their win/loss record with us.
