Sources: Luke Walton joins Cleveland Cavaliers as assistant 12:40 PM ET Adrian WojnarowskiSenior NBA Insider Close Host of The Woj Pod Joined ESPN in 2017 The Cleveland Cavaliers are hiring Luke Walton as an assistant coach, sources told ESPN on Tuesday. Walton joins coach J.B. Bickerstaff's staff after spending the past five-plus seasons as head coach of the Los Angeles Lakers and Sacramento Kings . Walton -- who played parts of his final two seasons as a player with the Cavaliers a decade ago -- brings significant championship coaching and playing experience to a Cavaliers franchise on the rise in the Eastern Conference. Under Bickerstaff, the Cavaliers made a dramatic rise in the conference into the play-in tournament. The Cavaliers' young core -- including All-Star guard Darius Garland , All-Rookie forward/center Evan Mobley and the burgeoning 7-footer Jarret Allen -- are expected to make Cleveland contenders to move into the conference's elite next season. Walton, who was dismissed after a 6-11 start with the Kings in November, was part of an NBA championship coaching staff with Golden State under Steve Kerr in 2015. He won two titles -- 2009 and 2010 -- as a member of the Lakers. Bickerstaff signed a long-term extension as the Cavaliers' coach in December.
