Heat rise to top after perfect week

There is a very simple reason to put the Heat at the top of this week's Power Rankings: They are the only team not to lose in the last week, going 5-0 to improve to 8-1 since dropping three consecutive road games.

The most impressive of the five victories was Sunday's nail-biter over a Chicago team missing Luol Deng, knocking the Bulls from the top spot. The Thunder seemed like the best bet to succeed the Bulls until falling to the Clippers on Monday. That outcome ended Oklahoma City's four-game winning streak and capped a strong month for the Clippers, who climb to fourth this week.

(All stats and records are through Monday, Jan. 30 unless otherwise noted.)
