Disorder on the court might awaken Celtics

BOSTON—There is no such thing as a perfectly harmonious NBA season because there are too many strong personalities in play, too many games that create too many opportunities for slumps to show up, too many moments when things can get slightly off the rails.

Good teams fight through them and survive; bad teams succumb to them and get worse. That’s how the separation in a franchise’s fortunes generally comes about.

Maybe there’s a rock-bottom moment: some spat becomes public, putting private feelings out in the open.
