Warriors coach Steve Kerr entered the summer with two openings on his coaching staff. Both slots have been filled, Kerr confirmed late Friday night.

A month after hiring Mike Brown as top assistant, Kerr this week turned to veteran shooting guard Willie Green as player development coach. Green replaces Theo Robertson, who took a coaching job with the Lakers, where he will work under Luke Walton, formerly Kerr’s top assistant.

“Great guy, young enough to get out there and play 3-on-3,” Kerr, in a text message to CSNBayArea.com, said of Green. “He’ll be great.”

Green, who on Thursday celebrated his 35th birthday, spent 12 seasons in the NBA, ending his career last season with the Orlando Magic. The 6-foot-4 shooting guard spent his first seven years with the 76ers, who acquired him on a draft-night trade with the Seattle SuperSonics in 2003. Green also played with the New Orleans Hornets, Atlanta Hawks and Los Angeles Clippers.

Green is one of the most respected players in the league. His arrival completes the staff, as Brown, a three-time head coach, will replace Walton as top assistant.

The coaching staff is composed of Kerr, Brown, veteran coach Ron Adams and former NBA player Jarron Collins. The player-development staff, which serves in an auxiliary capacity, is composed of Bruce Fraser, Chris DeMarco and Green.
