4: Luxury tax teams can't acquire buyout players
This rule is much more consequential for a rebuilding team like the Spurs. With the Spurs well under the salary cap, they became the ideal trade partner for organizations over the cap. Rumors suggested the Spurs could have been a landing spot for Russell Westbrook and his massive contract at the deadline. Had they acquired him, they would have waived him, allowing him to sign with a contender.
Under the new CBA, the Spurs could still acquire those expiring contracts and waive them. However, those players can't sign with luxury tax teams like the Clippers. That likely won't affect the Spurs next season since they will still be rebuilding. But when they are back in the playoff fold, it could help them. It wasn't long ago that the Spurs were viable options for buyout candidates, but they often got passed over for teams like the Lakers and Heat.
Thanks to this new rule, a small-market team like San Antonio would have a better chance of signing those players. If the Spurs get their hands on the number one pick in the 2023 NBA Draft and a certain 7'3" prospect, this CBA provision could help them add cheap veteran talent to their roster.
