text: I'm huge ROCKETS fan, and this questions comes up all of the time.  But I would go with Yao, because he is harder to replace than T-Mac, there are alot of great shooting guard/small forwards in the league.  With a trade or draft, you easily find a guard or forward who could put up 20-25 pts. a game.  While a Yao couldn't be replaced with a few seasons.  \n\nNaturally, it's easier to build around centers than smaller players.
