The NBA’s Collective Bargaining Agreement prevents a team from signing a player and then turning around and trading him shortly thereafter. If a club signs a free agent, without having reached an agreement on a sign-and-trade deal, then that club isn’t permitted to trade that player until December 15 or for three months after his signing, whichever is later.
Since most top free agents finalize new contracts in July, that December 15 date applies to many recent signees around the NBA. Several others can’t be traded until January 15, since they met certain criteria when they signed their new deals. And a few more, who signed after September 15, have unique dates when they’ll become trade-eligible, since the three-month anniversaries of their signings will fall after December 15.
Now that the calendar has turned to November 8, we can add a new category to that list of players with trade restrictions.
