2007-08 Houston Rockets
A 15-17 start certainly didn't suggest the Rockets were capable of putting together a dominant run. But with complementary players like Rafer Alston and rookie forwards Luis Scola and Carl Landry supporting stars Tracy McGrady (pictured) and Yao Ming (before he got hurt), the Rockets went unbeaten for seven weeks. And they sustained the streak even after losing Yao (foot surgery) for the season 12 games into it. The streak was snapped March 18 in a 94-74 home loss to the Celtics.
