The Pelicans are also receiving several draft picks in the the deal, according to Tim Bontemps, but none are coming from the Pistons.
Thon Maker hasn't lived up to expectation as a member of the Bucks, but the Pistons hope a change of scenery may invigorate him.
First reported by ESPN's Adrian Wojnarowski and Zach Lowe, the Bucks will be acquiring veteran forward Nikola Mirotic in a three-team deal between the Bucks, the Detroit Pistons and the New Orleans Pelicans.
In 35 games (no starts) this season with Milwaukee, Maker, 21, averaged 4.7 points and 2.7 rebounds while playing just 11 minutes per night.
Originally selected with the 23rd overall pick in the 2011 NBA Draft, Mirotic, 6-foot-10, holds career averages of 12.3 points, 6.0 rebounds and 1.3 assists per contest, appearing in 305 career games with both the Pelicans and Chicago Bulls. He is in the final year of a contract that pays him $5.4 million this season and will become an unrestricted free agent in the summer.
Johnson, 22, is averaging 7.5 points and 3.6 rebounds in his fourth National Basketball Association season with Detroit. The Bucks came into day with the best record in the East at 39-13 and the 76ers (34-20) sit six games back in fifth. He was part of the team's second unit when Ersan Ilyasova was injured, but forward D.J.
Maker has been benched for much of the season and requested a trade.
Smith was acquired by the Bucks from the Wizards in a three-team trade on December 7, 2018.
