The Milwaukee Bucks are finalising a deal to make Toronto Raptors assistant Adrian Griffin the franchise’s next head coach, multiple media outlets reported on Saturday.

He will replace Mike Budenholzer after his five-year stint in Milwaukee ended with the top-seeded Bucks losing to the Miami Heat 4-1 in the first round of the playoffs.

Griffin, who spent the last four seasons as an assistant in Toronto, takes over a team that finished the season with an NBA-best 58-24 record and two-time MVP Giannis Antetokounmpo.

According to ESPN, Bucks talisman Giannis Antetokounmpo met with each of the three finalists – Griffin, former Raptors head coach Nick Nurse and Golden State Warriors assistant Kenny Atkinson – before general manager Jon Horst made his final decision.

Griffin began his coaching career in Milwaukee, where he was an assistant under Scott Skiles from 2008-10. He was also an assistant with the Chicago Bulls, Orlando Magic and Oklahoma City Thunder before joining the Raptors' staff.

The 48-year-old won an NBA title in 2019 with the Raptors after Toronto eliminated Milwaukee in the Eastern Conference finals.

Griffin played for five franchises during his nine-year career on the court and was a part of the Dallas Mavericks' run to the Finals in 2006.

Replacing Budenholzer with Griffin is likely just the first move in a key offseason for the Bucks.

Antetokounmpo has two years left on his deal but will be eligible for a contract extension in September.

Brook Lopez is a free agent, and Khris Middleton could also test the market if he declines his $40.4 million player option for next season.
