The Mavericks big man just completed the second season of his five-year, $158 million contract.

Nowitzki’s first assignment in Dallas will include assisting the team in its search for a new head of basketball operations and head coach.

The Celtics acquired Walker in a sign-and-trade with the Hornets in June 2019, when he agreed to a four-year, $141 million deal.

At the time, Walker was coming off his best season in Charlotte, averaging 25.6 points while playing in all 82 regular-season games in the 2018-19 season.

The Celtics’ trade was mostly based on where he is physically — not about his character, talent or relationships with the team, according to ESPN

The trade marked Brad Stevens’ first big move since being promoted from Boston’s head coach to GM after Danny Ainge exited the position
