The two teams tied for the league's top record return to work this week as the top two teams in ESPN.com's weekly NBA Power Rankings.

Crunch-time mishaps in the All-Star Game for both LeBron James and Dwyane Wade (don't forget D-Wade had one, too, with that late pass he fumbled out of bounds) can't dislodge the Miami Heat from the No. 1 spot they've occupied for five successive weeks.

The Oklahoma City Thunder, meanwhile, have rolled up 12 straight home wins that, combined with San Antonio's decision to essentially forfeit last Tuesday's visit to Portland, nudged the Thunder ahead of the Spurs into the No. 2 spot.

The New York Knicks' stay in the top 10 was short-lived thanks to losses last week to New Jersey and Miami, but that opened up an opportunity for the Houston Rockets to sneak into the No. 10 slot ... despite the Rockets' curious inability to beat the Minnesota Timberwolves.

All-Star Weekend, as always, pushed the Power Rankings to Tuesday this week, but you can check back every Monday for the rest of the regular season for the latest fresh and nonautomated pulse-take of the league's 30 teams, which is compiled with Ricky Rubio-esque dishing from ESPN Stats & Information and the Elias Sports Bureau.
