The Rockets won their 19th straight on Monday night against the Nets. Two weeks after big man Yao Ming went down for the season with a fractured foot, the Rockets are still undefeated. Since Yao's departure, the Rockets have played even more as a cohesive unit led by star Tracy McGrady.

Does center Dikembe Mutumbo's defensive presence and selfless offense add a new dimension to Houston? Think about this for a second, if Dikembe makes the team better defensively and he doesn't demand the offensive touches that Yao did, does he make McGrady and cast better?
