Player movement doesn't end at the trade deadline.
Teams can come to agreements with players and buy out their contracts up through March 1, which allows them to hit waivers and then become free agents. As Larry Coon writes in his wonderful CBA FAQ:
After the player clears waivers, he and his former team are free to go their separate ways. There is a quid-pro-quo between the player and team regarding contractual obligation and salary -- in exchange for gaining his freedom, the player agrees to give the team a break on the remaining salary he is owed.
Buyouts don't happen with alarming frequency, and it's not too likely that many high-quality players are allowed to hit waivers during the same season. This 2013-14 seems to be a bit different, though, as teams are getting smarter about contracts.
Eight players have either been bought out and failed to land on a team yet or are heavily rumored to be entering the free-agent-pool in the near future. All eight should find another landing spot (assuming the buyouts are completed), but where will they go?
Will they all find their way to contenders? Will they just look for opportunities to play?
Be conscious of the fact that few teams are in position to add more than one player for the stretch run, so don't just expect every player to be projected to join the Miami Heat. They can't have everyone, despite what some fans and media members might lead you to believe.
