According to Keith Smith of Spotrac, the Celtics also received two future second-round picks in the deal from the Pistons. Smith also noted that the Celtics should now be in range to utilize the $5 million MLE by dropping back in the draft and out of the first round.
The Celtics had acquired the 25th pick in the deal that sent Marcus Smart to the Memphis Grizzlies and brought Kristaps Porzingis to the Celtics. Danilo Gallinari, Mike Muscala, and the 35th pick were also sent to the Washington Wizards in the three-team deal.
UPDATE: The Celtics have traded the 34th pick to the Sacramento Kings for pick 38 and a future second-round pick, according to Shams Charania of The Athletic.
