Yeah it was the Bryn trade that was in January.
Exact timeline of Spurs transactions last season, since there always seems to be confusion:
-Aug 6: We take part in that big 5 team trade that send Westbrook to the Lakers. Spurs got Wizards SRP and Chandler Hutchinson for Nikola Milutinov
-We trade Drew and Thad to the Wizards 2022 SRP for Dragic and the pick that became Branham
-We trade Derrick for Romeo, Josh, the pick that became Blake, and a top-1 protected swap in 2028
-June 30: We trade DJM for Gallo, and all dem picks
