Udoka has spent his entire coaching career as an assistant under Gregg Popovich in San Antonio, helping the team reach a pair of NBA Finals while winning a championship in 2014. He handled head-coaching responsibilities for the Spurs in both the 2013 and 2014 Las Vegas Summer Leagues, as well.
During his time under Popovich, a five-time NBA champion, Udoka learned that developing relationships with the players is the most important aspect of the role, per ESPN's Francis Okupa:
"Anybody can do Xs and Os and game plan for a team and scheme. Pops got all the bases covered, he's great in all areas but he's the best at relating to the players. Building a relationship with those players.
"Obviously, showing he cares for them is a big part of it. That's the thing I'll probably take away the most, the overall relationship with players. Once they know you care about them you can coach them a certain way and they allow you to coach them, but if it was that easy anybody that has a job would be able to coach guys and that's not always the case."
Udoka has a decade's worth of experience learning from Popovich as both a player and an assistant coach. Now, he will have the opportunity to reunite with Brown, who was previously with the Spurs, as well.
As The Athletic's Rich Hofmann noted, this move could help Udoka become a head coach one day:
Former Sixers assistant Lloyd Pierce was hired by the Atlanta Hawks in 2018.
Meanwhile, ESPN's Adrian Wojnarowski reported Will Hardy is expected to take on a more prominent role on the Spurs' coaching staff following Udoka's departure.
