Monty Williams, a former NBA player who has spent over the last decade along the sidelines, has signed up for the Philadelphia 76ers as Brett Brown's lead assistant.

As reported by ESPN's Adrian Wojnarowski, Williams, who had served as the San Antonio Spurs vice president of basketball operations the last two seasons, has opted to leave the front office and head on over to the Sixers' bench.

The 46-year-old will replace former Sixers assistant Lloyd Pierce, who took on the head coaching job with the Atlanta Hawks.

Williams has had his fair share of coaching experience in the NBA. As the head coach of the New Orleans Pelicans, he guided the team to two playoff appearances: 2010-11 (his first season) and 2014-15 (final season). He accumulated a win-loss record of 173-221 with the team.

After his five-year stint in New Orleans, he moved to the Oklahoma City Thunder where he served as associate head coach.

Outside the NBA, Williams was also part of Mike Krzyzewski's USA Basketball coaching staff in 2016 where they won the gold medal.

In fact, this is a homecoming for Williams. In his last season as a player, he suited up for the Sixers in the 2002-2003 season. He was the 24th pick in the 1994 draft. In nine seasons in the NBA, he played for the New York Knicks, Spurs, Denver Nuggets, and Orlando Magic.
