New Orleans Pelicans Coach Monty Williams will be joining the U.S. Olympic men’s basketball team as an assistant coach, a league source confirmed Monday morning. Considering one of the top young defensive coaches in the NBA, Williams will work the next three years under coach Mike Kryyzewski. Williams will replace New York Knicks Coach Mike D’Antoni, while Chicago Bulls Coach Tom Thibodeau will be replacing former Portland Trail Blazers Coach Nate McMillan. The official announcement of the hirings is expected to occur later on Monday. The Pelicans will hold a news conference at 3:30 today involving Williams, the team announced. D'Antoni and McMillan had been assistant under Krzyzewski on Team USA since 2005 and they won two gold medals. With their departures, the only holdover from Krzyzewski's previous staff is Syracuse Coach Jim Boeheim.
