One game. That is all that now separates the 40-10 San Antonio Spurs from the 41-9 Detroit Pistons. But the two best teams in the NBA now appear to be on diverging paths, since getting off to to the best starts in their respective franchise histories.

Today both the Spurs and the Pistons played in nailbiters. But while the Spurs came back from 5 points down with 1:35 left to beat the Pacers, the Pistons squandered a 7-point lead with 4-1/2 minutes left to lose to the Miami Heat. (You may recall, the Heat lost to the Mavericks last Thursday by 36 points.)

While the Spurs have won 9 games in a row and the last 13 out of 14, the Pistons have lost 4 out of their last 8 games, since having their 11-game winning streak ended by the New Jersey Nets. (You may also recall, the Pistons lost last Sunday to the Indiana Pacers, who lost to the Spurs today.)

The Spurs are known as a team that gets better as the season progresses. As for the Pistons, they appear to be on a different path.
