<P> The tight salary - matching rules of the 2005 CBA often required what NBA cap analyst Larry Coon called "trade ballast"--extra players added to a deal solely for salary matching, who would typically be waived by their new teams . Under that CBA, such players were restricted from rejoining their original teams for 30 days during the season or 20 days in the offseason . This led to what Coon called "wink - wink deals where players are traded with the full expectation of returning later ." A notable example of such a deal occurred in the 2009--10 season, in which the Cleveland Cavaliers included Zydrunas Ilgauskas in their trade with the Washington Wizards for Antawn Jamison . Ilgauskas was waived a week later without ever appearing in a game for the Wizards, and re-signed with Cleveland after the 30 - day waiting period passed . Since the 2011 CBA, a player acquired in a trade and waived by his new team cannot re-sign with his original team until one year after the trade or July 1 after the expiration of his contract, whichever is sooner . </P> <P> Certain players in the first few months of a new contract are subject to base year compensation (BYC). The intent of BYC is to prevent teams from re-signing players to salaries specifically targeted to match other salaries in a trade (in other words, salary should be based on basketball value, not trade value). A BYC player's trade value as outgoing salary is 50% of his new salary, or his previous salary, whichever is greater . BYC applies only to players who re-sign with their previous team and receive a raise greater than 20% . It also applies only when (and as long as) the team is over the salary cap . Since the 2011 CBA, players subject to BYC cannot be traded before January 15 except in a sign - and - trade, and BYC is only applied to outgoing salary in sign - and - trade deals . </P> <P> NBA teams can release a player to the waiver wire, where he can stay for 48 hours (during the regular season). While he is on waivers, other teams may claim him, for his existing salary . If he is not claimed, he is said to have "cleared waivers", and is treated like any free agent, able to sign with any team (with the special restriction noted above for players who were traded and then waived). </P> <P> Players waived after March 1 are not eligible to be on a team's playoff roster . The deadline was March 23 during the lockout - shortened 2011--12 season . </P>
