Trade Restriction for Newly Signed Players

The NBA's Collective Bargaining Agreement includes a provision saying that after a free agent signs with a team, he cannot be traded for 3 months or until December 15, whichever is later.

This is in place so a team cannot just sign a player off-the-street and then include them in a trade to make the numbers work.

Some current examples include: Earl Boykins, Damon Stoudamire, Chris Webber, and DJ Mbenga.
