Building a title team quickly through deals - as in 2007 - is woefully miscast as an "anomaly."
It is, in fact, FAR more common a rebuilding mode - whether it be through free agents or trades - than anything involving the alleged "fun" of playing the lottery tickets known as draft picks.
Miami has done it successfully, and I laugh at the characterization of that by the draft-obsessed as "cheating."
Dallas has done it. The Lakers have built a franchise on it. San Antonio seems to be able to retool quite easily around its aging core without bottoming out, as the Celtics seem intent on doing.
And no one has ever said it has to occur in one season. But it can. And it does, too often to warrant the semantic designation of a rarity.
