Change coming for Celtics?

I wrote about the Spurs' recent spinning of their tires on Monday, but it's amazing how many contending teams I can say the same thing about. The Spurs are a disappointing 8-8 since Jan. 1, but so is Dallas. They have company: Orlando is 10-9 since Christmas, and Atlanta is 10-9 in its past 19 games as well. Phoenix is 15-18 after starting the season 14-3, and Portland is 8-8 since Christmas. Even the Lakers are a very mortal 9-6 in their past 15 contests.

Suffice it to say I have an array of targets from which to choose for a "What's wrong with Team X?" column.
