West teams dominate top spots

The superstars headed East at the trading deadline, with Deron Williams leaving Utah for New Jersey and Carmelo Anthony going from Denver to New York. But after perhaps the most active swapfest in NBA history, the Western Conference controls the top spots in the Power Rankings.

The West's best are rolling. San Antonio is 49-10 with a franchise-record-tying 21-game home winning streak (though the injury bug finally bit the Spurs with the loss of Tony Parker for a couple of weeks). Dallas has won 16 of 17. And the Lakers, sensing that they could lose home-court advantage for two rounds, have refocused their enormous talent for the stretch drive, winning four in a row since the All-Star break.

Those three teams lead the way this week, followed by a foursome from the East.
