NEW YORK -- Mike D'Antoni is leaving the Brooklyn Nets, forcing Steve Nash to make another change on his coaching staff.

Nash announced the 70-year-old D'Antoni's decision in a statement Wednesday, saying having the two-time Coach of the Year was "invaluable" in his first season as a coach.

"I will be forever grateful for his guidance and will carry on a lifetime of lessons from the many years we've spent together," Nash said in the statement. "Our players and staff all benefited from this time in Brooklyn and we wish Mike, Laurel and their family the very best in what lies ahead."

D'Antoni won the 2005 Coach of the Year award in Phoenix when Nash was his point guard, then another in Houston in 2017. He has long been regarded as one of the NBA's best offensive coaches and helped the Nets reach the second round of the playoffs, where they lost to eventual champion Milwaukee in seven games.

The Nets already lost one assistant this offseason when Ime Udoka left to become Boston Celtics coach. David Vanterpool was hired to replace him.
