Sometimes Kevin Garnett's value isn't fully realized until he misses a game.

And with Garnett in the trainer's room for the first time this season, the Celtics not only turned permissive, but they once again lost their ability to execute down the stretch.

The result last night was a 98-88 loss at the Garden to Detroit, a game that ultimately went bad in all phases, including allowing the Pistons to stick open jumpers at a 47.3 percent efficiency rate and glaring ham-handedness from the free throw line (19-for-32, 59.4 percent).
