The Dallas Mavericks recently waived 2023 first-round pick Olivier-Maxence Prosper to make room to re-sign Dante Exum, giving them some much-needed backcourt help. Prosper likely wouldn’t have played much this season, and after they couldn’t find a trade partner for him, the Mavericks waived and stretched his contract. It was shrewd basketball business from Nico Harrison, especially since they were able to turn Holmes and a first-round pick into Daniel Gafford.
