This is what I've been advocating in a lot of larbird33's blow it up threads. Getting trade exceptions and assets to compete, if not this coming season then the one after it.
Acquiring the exceptions is feasible. For example pierce and kg to Dallas for Marion. Pierce to Cleveland and kg perhaps to SA who has cap space. Nearly 18 mill. In those trades try to add lee to Memphis in a salary dump to increase the exception.
Use the exceptions via s+t, like last year with Steve Nash to lakers, to acquire, for example, big al and josh smith. Both guys get deals worth 10-12 mill annually. After what I saw Indiana do in the ECF,a core four of rondo, green, smith, and big al surrounded by other assets in the form of Bradley, melo, sullinger, and draft picks would have the ammunition to compete for a title.
Teams like 2004 pistons are becoming the way to build a contender now.
