Essentially, Lin is playing well and replaced Bibby and Douglas who were playing horribly. Other teams who could improve by replacing bad players: Minnesota, New Jersey, the Lakers and Orlando. Deep teams who will find it difficult to improve by replacing players: Bulls, Denver, Houston, Philadelphia and San Antonio. Relevant quote for Bulls fans: "Take the Bulls, for instance, who amazingly don't have a single minute played this season from a player with a PER below 12. (At the moment, at least -- Ronnie Brewer and Brian Scalabrine are very close.) ... The glass-half-empty look at their depth, however, is that there isn't the opportunity for the kind of explosive improvement from a single move that we saw from the Knicks with Lin."
