The Bucks lose depth in their frontcourt and will probably try to find a way to replace Maker.
In his third year in the league, Maker is averaging 14.4 points, 8.4 rebounds, 1.6 blocks per 36 minutes.
Maker, the 10th overall pick in the 2016 draft, showed flashes in his two-plus years with the Bucks, but could never gain a foothold in the regular rotation. In 276 games with the Pistons, he averaged 7 points and 3.5 rebounds per game. They are both from tiny Kinston, North Carolina.
The Bucks are averaging 13.3 made 3-pointers per game, which ranks second behind Houston (15.4).

According to ESPN, Maker had told the Bucks he would prefer a trade to a team where he could have a larger role. The Sixers sent rookie guard Landry Shamet and four draft picks to the Clippers.
He was the 76ers' main target, but they also get 221cm giant Boban Marjanovic and forward Mike Scott from the LA side.
Bucks general manager Jon Horst has swung a trade deal for the second time in as many days. Maker has shot 33.3 percent from the 3-point line this season. 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.
A starting five of Simmons, JJ Redick, Butler, Harris and Embiid will bring the team closer to competing for the eastern conference title although the Sixers may need to make more moves to boost their bench.
