2. Defense

The Pistons have never been pretty. Their game has always revolved around defense. The problem with that? The Celtics play defense better. Boston is holding opponents to 86.1 points and 40 percent shooting in the playoffs. Detroit has held opponents to 87.8 points and 43.9 percent shooting. Not only are the Celtics going to win, but they're going to beat the Pistons at their own game.
