At 9-3, the Oklahoma City Thunder lead the middling teams of the Northwest Division by three games. Of the other four teams in the Thunder's division, only Portland, at 5-6, does not sit at a .500 record over three weeks into the 2012-13 NBA season.
In the rest of the Western Conference, the 8-2 Memphis Grizzlies lead the Southwest Division, followed by the 9-3 Spurs. The Clippers lead the Pacific Division at 8-3, while the Lakers have chipped back from their 1-4 start to a .500 record at 6-6. Dallas, without Dirk Nowitzki, and Golden State are also over .500.
In the Eastern Conference, the Miami Heat lead with a 9-3 record. No surprise there - that the Knicks lead the Atlantic at 8-2, that the Bucks lead the Central at 6-4, and that the Charlotte Bobcats, at 6-4, will match their season total of seven wins unless they manage to lose 72 games in a row.
