Trade Overview and Key Terms
On January 29, 2018, the Detroit Pistons traded Blake Griffin, Brice Johnson, and a protected 2018 first-round pick to the Brooklyn Nets in exchange for Andrew Nicholson, Marcus Morris, and a 2019 second-round pick. The trade was later voided by the Nets after Griffin failed his physical, and Griffin was instead traded to the Boston Celtics on January 31, 2018, for a protected 2019 first-round pick and a 2018 second-round pick. The deal was part of the Pistons' rebuild under general manager Ed Stefanski and owner Tom Gores, who were clearing veteran salary to acquire young assets and draft capital. The move freed up approximately $19.5 million in guaranteed salary for the 2018-19 season and removed Griffin's $19.5 million player option for that year. The voided Nets trade and subsequent Celtics deal are documented in NBA transaction records and reported by ESPN and The Athletic.
The Pistons received Marcus Morris, who provided frontcourt depth and three-point shooting, along with a second-round pick. The failed physical clause in the Griffin trade is a standard NBA mechanism that allows teams to back out of a deal if a player fails a team-designated medical exam. The NBA's collective bargaining agreement permits teams to void transactions when a physical reveals a condition that materially affects performance or durability. Griffin's reported knee issues and declining mobility were cited as factors in the voiding of the initial Nets trade. The Pistons' front office used the trade to pivot toward a youth-oriented roster built around draft picks and prospects, a strategy that aligned with their long-term salary-cap planning.
Salary, Draft Assets, and Roster Impact
Griffin's salary with the Pistons in the 2017-18 season was $19.5 million, making him the team's highest-paid player at the time of the trade. The voided Nets trade would have sent Griffin and a first-round pick to Brooklyn, while the Celtics trade sent Griffin and a second-round pick to Boston in exchange for a protected first-round pick. The Pistons' final return from the Griffin trade was the second-round pick from Boston, which became the 53rd overall selection in the 2018 NBA Draft, used to select Ray Spalding. The trade did not include any cash considerations or additional player swaps, and no salary was retained by Detroit after the deal. The move reduced the Pistons' payroll flexibility heading into the 2018 offseason and signaled a commitment to a full rebuild.
The trade also affected the Pistons' cap space and luxury-tax situation. By moving Griffin, Detroit avoided paying the repeater luxury-tax penalties that would have applied if they retained him and exceeded the tax apron. The NBA's luxury-tax system imposes escalating surcharges on teams that exceed the tax threshold by a margin, and repeated overages trigger higher rates. The Pistons' payroll for the 2018-19 season dropped below the tax line after the trade, giving them room to maneuver in free agency and on draft night. The team used that flexibility to sign veterans on short-term deals and to focus on draft capital accumulation, a strategy that continued through the 2019 and 2020 drafts.
Post-Trade Career and League Context
After the trade, Blake Griffin played for the Boston Celtics, Detroit Pistons (in a separate 2018 offseason sign-and-trade), and the Brooklyn Nets before retiring in 2023. His final NBA season was with the Nets in 2022-23, where he averaged 3.8 points and 3.3 rebounds in 41 games. The Pistons, meanwhile, continued their rebuild and drafted Cade Cunningham with the first overall pick in the 2021
