Chicago acquired the rights to restricted free agent Mike Bratz from San Antonio on March 8, 1983 for a 1983 fourth-round pick that became No. 90 Brant Weidner. Bratz played 15 regular-season games for the Bulls, all off the bench, before signing with Golden State that September. Chicago then received a 1984 fourth-round compensation pick from the Warriors and used it at No. 77 on Mark Halsel, who never played in the NBA. Weidner played eight regular-season games for San Antonio in 1983-84 and never started. Both returns were small, but Chicago received more direct games from Bratz plus one additional compensation asset, giving the Bulls a narrow hindsight edge.
Basketball-Reference's Chicago, San Antonio and league transaction ledgers agree on the March 8, 1983 terms. The Bulls acquired the rights to restricted free agent Mike Bratz and sent the Spurs a 1983 fourth-round pick. That selection eventually became No. 90 Brant Weidner.
Bratz appeared in 15 regular-season games for Chicago to finish the 1982-83 season. He made no starts and averaged 9.3 minutes, 2.6 points and 1.5 assists. That is a limited return, but it was still immediate NBA rotation value from a fourth-round pick. Bratz did not remain with Chicago. He signed with Golden State on September 30, 1983 and went on to play all 82 games for the Warriors the following season.
Because Bratz signed with Golden State as a veteran free agent, Chicago received a 1984 fourth-round compensation pick. The Bulls used that selection at No. 77 on Northeastern forward Mark Halsel. Halsel never appeared in an NBA regular-season game. This review therefore gives Chicago credit for the extra transaction asset created by Bratz's departure, but not for any on-court value from Halsel.
The Spurs used the original 1983 fourth-round pick at No. 90 on William & Mary forward Brant Weidner. Weidner appeared in eight regular-season games for San Antonio in 1983-84, made no starts and averaged 4.8 minutes, 1.0 point and 1.4 rebounds. Those eight games were the entirety of his NBA career.
Neither side found a long-term player. San Antonio received eight games from Weidner, while Chicago received 15 from Bratz and later generated a fourth-round compensation pick when Bratz left. The compensation pick ultimately produced zero NBA games, so the edge should stay modest. Still, Chicago extracted more total transaction utility from the original fourth-round asset.
Bulls Win, C+/C. Chicago receives a C+ for 15 Bratz games plus a later compensation pick. San Antonio receives a C because Weidner reached the NBA but played only eight games and never started. This is a narrow realized-value win, not a franchise-changing transaction.
