The Authoritative Ledgers Show Peck for a Second-Round Pick
Basketball-Reference's Phoenix, league and executive transaction records agree on the June 9, 1980 deal: Dallas sent Wiley Peck to Phoenix for a 1981 second-round pick that later became Elston Turner. The legacy Dallas source record also contains a generic future-considerations line. None of the reviewed authoritative transaction ledgers lists that extra term, so this review preserves it as an unverified legacy-source detail rather than scoring it.
Peck Never Played for Phoenix
Peck had played 52 games for San Antonio as a rookie in 1979-80 before Dallas selected him in the expansion draft and immediately moved him to Phoenix. The Suns waived Peck on September 8, 1980. Basketball-Reference records no Phoenix regular-season appearances for him, and his 52-game Spurs season remained his entire NBA playing career. That leaves Phoenix with zero direct on-court production from the acquired player.
Dallas Used the Pick on Elston Turner
The second-round pick landed at No. 43 in the 1981 draft, where Dallas selected Elston Turner. He immediately became a useful rotation wing. Turner played 80 games as a rookie, starting 62 and averaging 8.3 points, 3.8 rebounds and 2.4 assists in 25.0 minutes. He followed with 59 games in 1982-83 and 47 more in 1983-84. That gives Dallas 186 regular-season Turner games across three seasons, including 79 starts and 3,411 minutes. He later continued his NBA career with Denver and Chicago, but this review stops Dallas's realized value at his Mavericks tenure.
Why Dallas Wins Clearly
Phoenix surrendered a second-round pick for a player who never appeared in a regular-season game for the Suns. Dallas turned that pick into three seasons of useful wing depth and a rookie-year starter. The unverified future-considerations line is not needed to decide the trade. Even grading only the terms corroborated by Phoenix and league records, Dallas received substantially more realized basketball value.
Final Verdict
Mavericks Win, B+/F. Dallas receives a B+ for 186 Turner games across three seasons, including 62 rookie starts. Phoenix receives an F because Peck was waived before playing a regular-season game for the Suns.
