Boston acquired Chris Ford and Detroit's 1981 second-round pick on October 19, 1978 for Earl Tatum. Ford played 309 regular-season games over four Celtics seasons, started 201 of them and was a 75-game starter on Boston's 1980-81 championship team. The extra pick became No. 25 Tracy Jackson, who appeared in 11 games for Boston before the Celtics sold his rights to Chicago in December 1981. Tatum played 76 games for Detroit in 1978-79 and averaged 7.8 points in 15.7 minutes. Detroit received a usable rotation season, but Boston's four years of Ford plus the additional draft asset produced the larger realized return.
Boston and Detroit transaction records agree on the October 19, 1978 exchange. The Celtics sent Earl Tatum to the Pistons and received Chris Ford plus a 1981 second-round pick. The draft asset stayed with Boston long enough to become the No. 25 selection in 1981. The Celtics used it on Notre Dame guard Tracy Jackson.
Ford played 78 games for Boston immediately after the trade in 1978-79 and averaged 15.6 points, 4.7 assists and 3.3 rebounds. He stayed with the Celtics through 1981-82. Across four Boston seasons, Ford appeared in 309 regular-season games and started 201. His role changed as the roster improved, but he remained a real rotation piece throughout the transition from a 29-win 1978-79 team to a championship roster. The most important season is 1980-81. Ford played all 82 games, started 75 and averaged 33.2 minutes. Boston won the NBA championship that season, making Ford a substantial contributor to the title team rather than a fringe roster holdover. He also continued into 1981-82, playing 76 games and starting 53 before his NBA career ended.
Boston's second asset became Tracy Jackson at No. 25 in the 1981 draft. Jackson played 11 games for the Celtics in 1981-82, totaling 66 minutes. On December 9, 1981, Boston sold his player rights to Chicago. That outcome is modest, and this review does not inflate the pick as if Boston received Jackson's entire three-year NBA career. The direct Celtics value was 11 games plus whatever consideration came from the rights sale, whose amount is not documented in the reviewed Basketball-Reference transaction record.
Tatum played 76 games for Detroit in 1978-79 after the trade. He logged 1,195 minutes and averaged 7.8 points, 1.6 rebounds and 0.9 assists. That is meaningful short-term return. Tatum was not a non-factor, and Detroit received substantially more than a few appearances or an unused roster spot. The difference is duration and role. Tatum's Detroit value is concentrated in one season. Ford gave Boston four seasons, more than 9,000 minutes, 309 regular-season games and a starting role on a championship team.
The Celtics received the best individual asset in Ford and also retained the additional second-round pick long enough to turn it into an NBA player. Jackson's Boston contribution was small, so the pick is secondary to the grade. Ford carries the case. His 309 games, 201 starts and championship-season role create a much larger realized return than Detroit received from Tatum's 76-game season. Detroit still deserves credit for receiving a usable rotation guard. The result is not a zero-value loss; it is a clear Boston win created by Ford's longevity and championship relevance.
Celtics Win, A-/C+. Boston receives an A- because Ford became a four-year contributor and a regular starter on the 1981 champions, while the extra second-round pick added 11 Jackson games before his rights were sold. Detroit receives a C+ because Tatum supplied 76 useful games in 1978-79 but did not approach Ford's cumulative Boston impact.
