Given that Yao will be out for at least 6 weeks. Rox has to think about adding more talents to this team. However, in the future, Rox has to be prepared for the possibility that Yao would only play around 60 games per season. If you compare Yao's games per season vs. Shaq's games played per season, they are looking similar so far: http://www.nba.com/playerfile/shaquille_oneal/career_stats.html http://www.nba.com/playerfile/yao_ming/career_stats.html Big guys tend to get injuried during the season. Yao is 7'6", he is more prone to injury.
There is a thing in the NBA called the salary cap so its hard to get any good players when you have two players making the max. If you lose both of those players, your screwed. Only way to get cheap talent is through the draft.
