NBA Preview: Southwest 2. Houston Rockets Best-case scenario: Yao Ming and Tracy McGrady form the league's best inside-out combination, Stromile Swift gives the Rockets consistent defense and rebounding at power forward and the Houston backcourt complements the frontline with solid shooting and strong defense. The Rockets break through and win the division. Worst-case scenario: Yao and T-Mac don't quite click and Swift displays the mercurial nature that made him expendable in Memphis. The backcourt defends poorly and Houston's defense slips. The Rockets fade toward the .500 mark. Outlook: This is an emerging, well-coached team. The Big Two will be great, and Swift is the kind of athletic "four man" the Rockets desperately needed last season. If Houston gets solid play from newcomers Derek Anderson, Rafer Alston and Luther Head in the backcourt, watch out.
