According to Wojnarowski, the Bucks are sending Dellavedova, John Henson and 2021 first and second-round picks to the Cavaliers in exchange for George Hill and Sam Dekker.
The Milwaukee Bucks are reportedly trading the out-of-favour point guard back to Cleveland, where he was part of the 2016 National Basketball Association championship-winning Cavaliers.
The Cavaliers also received forward John Henson and 2021 first- and second-round picks from Milwaukee, and a 2022 second-rounder from Washington.
For The Athletic, CBA and salary cap expert Danny Leroux breaks down Friday's Cavs-Bucks-Wizards trade from each team's perspective for the near and long terms.
Affectionately known to Cleveland fans as "Delly", Dellavedova was a key member of the Cavs' 2016 title team before he signed with the Bucks later that summer.
Henson's departure also opens up more game time for Maker who started the season on the bench but has been playing more in recent weeks.
Hill (6-3, 188) appeared in 37 games (all starts) for Cleveland after being acquired by the Cavaliers on February 8, 2018, averaging 9.9 points, 2.5 rebounds and 2.8 assists in 27.4 minutes per game over that span. Dekker (6-9, 230), who was acquired by Cleveland on August 7, 2018, played in nine games (five starts) for the Cavs this season, averaging 6.3 points, 3.7 rebounds and 1.22 steals in 18.8 minutes per game. This season, he played in 14 games for the Bucks and averaged 5.6 points and 5.1 rebounds in 13.4 minutes per game. "Brings us veteran leadership, a guy that's won before, a guy that's going to push Collin (Sexton), control the game for the second unit and he'll make shots".
"I think it will be good for our team, not just for myself, but for our team".
In 12 appearances this season, Dellavedova is averaging 1.7 points, 0.8 rebounds and 2.4 assists per game.
Henson recently underwent surgery to fix a torn ligament in his left wrist.
Dekker, who starred at Wisconsin before becoming the No. 18 overall pick in 2015, has been out for more than a month with an ankle injury.
Sexton, the No. 8 overall pick in the June draft, has already heard stories about Dellavedova.
