A new week means it's time for our look at the best NBA teams of each conference and how they have fared this past week and what we can expect in the coming seven days. Have any teams fallen out of the rankings?

The Chicago Bulls may have the best record in the league but the Miami Heat are bearing down quickly and are now just a half-game back for the top seed in the Eastern conference

In the West, the Oklahoma City Thunder remain the team to beat and that doesn't appear likely to change any time soon. Kevin Durant and Russell Westbrook are tearing it up and show no signs of slowing down (Check out the Tuesday NBA pick on the Thunder and Jazz). 

What else is happening in the two conferences? Well... 

EASTERN CONFERENCE

Chicago Bulls (23-7 SU, 18-12 ATS)

Derrick RoseThe injury bug simply will not go away in the Windy City as Rip Hamilton remains out and Derrick Rose is now dealing with back problems. Still, the Bulls are 6-1 SU and 5-2 ATS over their last seven so nothing to really worry about I guess.

Miami Heat (22-7 SU, 14-15 ATS)

Winners of three straight and six of their last seven, the Heat continue to play terrific ball. They'll face a tough challenge against the Pacers this Tuesday though, that's for sure.

Philadelphia 76ers (20-9 SU, 18-10-1 ATS)

Are people waiting for the 76ers to start losing or something? There still seem to be non-believers out there but Philadelphia isn't paying any attention. The only worrying thing is they've lost three of their last four home matchups.

Indiana Pacers (17-10 SU, 13-14 ATS)

I know the Pacers have lost three straight but this team is still extremely talented. They'll figure it out soon. It helps that after their game against Miami, they'll play seven straight against teams with losing records.

Orlando Magic (18-11 SU, 16-13 ATS)

The last spot goes to the Magic, just barely (and I mean barely) above the Hawks and surging Celtics. Orlando's gone 6-2 SU over their previous eight games and scored a big double-digit win over the Heat this past week.

WESTERN CONFERENCE

Oklahoma City Thunder (21-6 SU, 15-12 ATS)

The Thunder are showing they can win both at home and on the road too. They have the conference's best road record at 12-5. Six of their next seven games will be in Oklahoma City however and I'm sure they're not complaining.

Serge IbakaSan Antonio Spurs (19-9 SU, 17-11 ATS)

No team is hotter than the Spurs, who've won seven consecutive matchups. Included in there was a 11-point win over the Thunder as well as another impressive double-digit victory, this time on the road over the 76ers.

L.A. Clippers (17-9 SU, 15-11 ATS)

Chauncey Billups may be lost for the season, but CP3 and the Clippers have adjusted decently well and are still winning games. Mo Williams will finally get the minutes he's been after so let's see how he does.

Dallas Mavericks (18-11 SU, 17-12 ATS)

Now that Dirk Nowitzki (averaging 25.7 PPG over last six games) is healthy and performing, the Mavericks are playing their best basketball of the season. They've won four in a row with three of those victories coming against Denver, Portland and the L.A. Clippers.

Denver Nuggets (16-12 SU, 16-12 ATS)

The Nuggets beat out the Lakers simply because they're much more balanced and their bench is miles better too. Nonetheless, Denver has lost five of six so they really have to turn it around in a hurry.
