Traded Player Exception: If a team trades away a player with a higher salary than the player they acquire in return (we'll call this initial deal "Trade #1"), they receive what is called a Traded Player Exception, also known colloquially as a "Trade Exception". Teams with a trade exception have up to a year in which they can acquire more salary in other trades (Trade #2, #3, etc.) than they send away, as long as the gulf in salaries for Trade #2, #3, etc. are less than or equal to the difference in salary for Trade #1. This exception is particularly useful when teams trade draft picks straight-up for a player; since draft picks have no salary value, often the only way to get salaries to match is to use a trade exception, which allows trades to be made despite unbalanced salaries. It is also useful to compensate teams for losing free agents as they can do a sign and trade of that free agent to acquire a trade exception that can be used later. Note this exception is for single player trades only, though additional cash and draft picks can be part of the trade.
