NBA Power Rankings: Celtics on top, Spurs move into top five

The top four in our power rankings did not change this week and the teams just kept on winning — including 13 in a row for Boston, but that will be tested Thursday night when they face the Warriors. The Wizards were the big climbers this week, jumping from 16 to 8 (although I may have had them a little low the week before). Boston keeps on doing it with defense, which remains the best in the NBA.
