The New York Knicks believed the San Antonio Spurs tampered with Kristaps Porzingis when he was still on their team.
The Knicks traded Porzingis to the Dallas Mavericks shortly before the 2019 trade deadline.
The Knicks felt justified in signing Marcus Morris after he committed to a deal with the Spurs due to that tampering belief concerning Porzingis. Morris and Rich Paul parted ways after the episode and the Spurs were upset with the Knicks.
Morris agreed to a two-year, $20 million deal with the Spurs and then signed a one-year, $15 million deal with the Knicks.
