What do the Rockets need to do? Avoid another serious injury to T-Mac. Light a fire under Yao. Hope that Bob Sura can heal quickly and return with his feisty game intact. Lose both Juwan Howard and Stromile Swift and bring in a banger. Get a quicker, bigger two-guard to replace David Wesley. Hope that Luther Head matures quickly enough (especially on defense) to put Wesley on the bench. Since Derek Anderson has recently been injured (what else is new?), another bench scorer must be found, one that can (unlike Jon Barry) create shots off his dribble. These changes involve more than cosmetic surgery and most likely can't be addressed until the off-season (when a replacement for Dikembe Mutombo must likewise be located). An immediate spark can be generated by replacing Jeff Van Gundy's petulant nonsense with a grown-up coach whom the players have to respect — like Paul Silas.
