All 30 NBA teams have been formally reminded by the league office that team owners, front office executives, coaches and other employees must keep the text from all contract-related communications with players and agents for one full year, sources initially told Marc Stein of the New York Times.

Shams Charania of The Athletic added more details with topics that must be preserved such as current or potential player contracts, transactions, potential endorsement or investment opportunities, the player's fit or future with the current or new team, as well as training, health and wellness.

The memo is part of the NBA's mission to reduce tampering.
