Yep, with the current culture of star players gravitating toward each other in big markets it's probably the only way for a team like Houston to have a chance of breaking out while maintaining their respectable win totals.
Right now the only ways up in the NBA seem to be:
* tank/suck for high picks
* be a big market team where FA's will come (NY/MIA/LA/"Brooklyn")
* do what Houston are doing
To be honest after the rose tinted glasses came off and you see Lin for what he is, me personally I took a lot more notice of his downsides like the poor FG% for a player who's main weapon is to attack the rim.
The stars aligned for Jeremy Lin in New York but unless MDA ends up taking over in Houston I don't think he's going to display all star qualities again.
