Cleveland and Milwaukee swapped future first-round picks on June 1, 1978. The Cavaliers received Milwaukee's 1978 first, which became No. 15 Mike Mitchell. Milwaukee received Cleveland's 1979 first, which landed at No. 4. Both teams ultimately extracted major value. Mitchell played 271 regular-season games for Cleveland across parts of four seasons, averaged 24.5 points in 1980-81 and made the 1981 All-Star team before being traded with Roger Phegley to San Antonio for Ron Brewer, Reggie Johnson and cash. Milwaukee never used the No. 4 pick on Greg Kelser. On draft day in 1979, the Bucks traded that slot to Detroit for the No. 5 pick and selected Sidney Moncrief. Moncrief became a Hall of Famer, five-time All-Star, five-time All-NBA selection, five-time All-Defensive selection and two-time Defensive Player of the Year for Milwaukee. Cleveland received an excellent star-level return; Milwaukee turned the future pick into a franchise cornerstone and gets the stronger hindsight result.
Cleveland, Milwaukee and the league transaction ledgers all record the June 1, 1978 exchange the same way. Cleveland sent its 1979 first-round pick to the Bucks and received Milwaukee's 1978 first-round pick. The Cavaliers used the incoming selection at No. 15 on Mike Mitchell.
Mitchell became an immediate rotation scorer. He played 80 games as a rookie in 1978-79 and then all 82 games in both 1979-80 and 1980-81. His third season was the peak of his Cleveland tenure: 24.5 points per game, 6.1 rebounds and an All-Star selection. Mitchell stayed with Cleveland for 27 more games in 1981-82 before the Cavaliers traded him and Roger Phegley to San Antonio for Ron Brewer, Reggie Johnson and cash. Across his Cavaliers tenure, Mitchell appeared in 271 regular-season games. This review does not assign the full Brewer-Johnson-cash package to Mitchell alone because Phegley was also outgoing, but the later trade confirms that Mitchell retained substantial asset value.
Cleveland's 1979 first became the fourth pick in the draft. The legacy archive record stops at Greg Kelser because Detroit ultimately selected him there, but Milwaukee did not simply make that pick and keep Kelser. On June 25, 1979, the Bucks traded the No. 4 pick to Detroit for the No. 5 pick. Detroit drafted Kelser at No. 4. Milwaukee moved down one slot and selected Sidney Moncrief at No. 5.
Moncrief became one of the defining players of the Bucks' 1980s teams. Basketball-Reference lists him as a five-time All-Star, five-time All-NBA selection, five-time All-Defensive selection and two-time Defensive Player of the Year. He also entered the Basketball Hall of Fame. The No. 4 pick acquired from Cleveland therefore did not merely become Kelser. It became the premium asset Milwaukee used to move down one spot and secure Moncrief. The distinction is essential because a simple Mitchell-versus-Kelser comparison badly understates Milwaukee's realized return.
This is not a case where one team won because the other side failed. Mitchell became one of Cleveland's best scorers of the period, made an All-Star team and gave the Cavaliers 271 games. A mid-first pick producing that level of direct value deserves a strong grade. Milwaukee's result was simply larger and longer lasting. Moncrief developed into a franchise cornerstone with elite two-way recognition for much of the decade.
Bucks Win, A+/A. Milwaukee receives an A+ because the Cleveland pick became the No. 4 slot, which the Bucks converted into No. 5 Sidney Moncrief, a Hall of Fame guard with five All-Star selections, five All-NBA honors, five All-Defensive honors and two Defensive Player of the Year awards. Cleveland receives an A because Mitchell played 271 games, made the 1981 All-Star team and retained later trade value. Both teams did extremely well; Milwaukee gets the edge because the pick became a true franchise-defining player. Confidence is high.
