NBA teams that have been eliminated from playoff contention merely play out the string at this point. Several players do exactly the same, but for an entirely different reason.
With the offseason rapidly approaching, there are a number of high-profile free agents who don't figure to be with their current teams at the start of next year. Some of these players look to land a long-term deal, while others merely want the prospect of a starting job and/or increased playing time.
Then there are those who are keenly aware that they're not part of their respective team's plans moving forward. In these cases, an amicable separation is best for all involved, especially for the player. As the saying goes, one man's trash can be another man's treasure.
