Something CBA related to the Ariza trades.
64. What happens when a player is released? What are waivers? What is the Stretch provision?Other rules related to waivers:
* Once a team puts a player on waivers, the waivers cannot be withdrawn.
* If a team requests waivers on a player after March 1, the player is ineligible to be included in the playoff roster of any team that subsequently signs or acquires him4.
* In the last season of a player's contract (or a season that may be the last due to an option or ETO) he must be waived in time for the 48-hour waiver period to elapse before the date of all 30 teams' final regular season games.
* Players claimed from waivers retain their Early-Bird rights (see question number 25) just as if they had been traded. If a player with full Bird rights is claimed from waivers, his status drops from full Bird to Early Bird.
* When a team trades a player who is subsequently waived by the receiving team, it cannot claim the player off waivers or re-sign the player until the one-year anniversary of the trade, or until the July 1 following the end of his contract5, whichever is earlier6.
* A "buyout" is actually a combination of altering the player's contract to change the guarantee and/or payment schedule, then waiving the player (see question number 66).
* A player's non-protected salary is removed from the team salary as soon as the team requests waivers.
* If a team claims a player on waivers, it cannot trade the player for 30 days if the claim was made during a season. If the player was claimed during the offseason, he cannot be traded until the 30th day of the following regular season.
* The 48 hour waiver period continues into and through the July Moratorium (see question number 105). Teams are allowed to waive players and claim waived players during the Moratorium. Salaries adjust at the start of the Moratorium, so waivers initiated on June 29 or 30 may require a different salary amount to claim.
* A system of "partial waivers" is available under certain circumstances (see question number 68).
* If a team chooses to stretch the cap hit of a waived player's salary (see question number 65), it cannot re-sign or re-acquire the player until the end of the original term of the contract.

6 Interestingly, a player can be traded to a third team, waived by the third team, and be eligible to re-sign with his original team before the waiting period expires. While this has not happened in practice, the league clarified its interpretation of this rule in 2017, in regard to a possible instance with Andrew Bogut.
If I have it correct, Ariza could go back to Portland if he is waived by Detroit.
