The 76ers have yet to announce – by way of an official press release – the members of coach Brett Brown’s staff, even though Lloyd Pierce, Chad Iske, Billy Lange, Greg Foster and Curtis Sumpter have been visible figures ever since training camp.

So when a reporter asked Brown after Thursday’s practice for the identity of the guy under the far basket, wearing a Sixers T-shirt, working with Spencer Hawes, it was somewhat surprising that Brown revealed who he was.

“That’s Vance Walberg,” Brown said.

Walberg, who most recently was on George Karl’s staff last season with the Denver Nuggets, is regarded for developing the dribble-drive motion offense. A California-based high school coach from 1978-2002, Walberg was the head coach at Fresno City College from 2002-2006 and Pepperdine from 2006-08, worked as an assistant at UMass from 2008-11 before joining the Nuggets last year.

“If you looked on Google, you would see Sports Illustrated articles and other articles on him,” Brown said of Walberg. “He’s very renowned and researched in the dribble-drive game. That’s his claim to fame. Many articles declared him to be one of the most innovative coaches in all of basketball. Coach (John) Calipari has implemented his system at Kentucky. For me, I’m interested in that attack game, that drive-and-dish game, that proactive game. The combination of that and pick-and-roll is the future of the game, and I want to learn more. So he’s been with us and he’s been fantastic."

One of these days, the Sixers will unveil who is serving on Brown's bench. It's yet to be determined if Walberg is one of them.

Villanova product Curtis Sumpter, who attended the 76ers’ training camp opener Saturday, could be joining first-year coach Brett Brown’s staff with the Sixers.

“It’s looking like that,” Brown said.

Brown said the 29-year-old Sumpter, upon being officially hired, would handle player development and video room duties.

“He’s come in to look at a combination development role and video intern role, so it’s a hybrid,” Brown said of Sumpter. “He’ll spend time in the video room, learning the NBA and helping us out on the court guarding people. A little bit of coaching, but a little bit of everything. I feel like I see something special in him, with his eyes and his demeanor. 

“He’s a high-character guy, and I’m happy to groom him, but he’s under review at the moment.”

Sumpter had been working at Villanova since August 2012, as a student-athlete development assistant under coach Jay Wright. The forward played with the Wildcats for four seasons in five years, from 2002-2007, due to injuries. He finished with 1,651 points and 794 rebounds.

His post-college career also included professional stops in Germany and France.

The 76ers have agreed to terms with assistant coach Chad Iske, according to a report by Yahoo! Sports, adding a second assistant to Brett Brown’s staff.

Iske, who previously coached with the Denver Nuggets, is regarded as a player-development coach who also lends a hand in game-to-game preparation. He’s Brown’s latest coaching-staff addition, joining Memphis assistant Lloyd Pierce, who the Sixers hired Aug. 25.

Hired as the Sixers’ coach Aug. 14, Brown had said he’d like to have his coaching staff in place before the start of September.
