Just grabbed this of Wiki, sorry if it's too big. Seems he has been around a fair bit and overlooked for a fair few head coaching gigs but a lot of experience none the less.
I can always appreciate adding some more experience to the coaching staff,
Turner later moved to the NBA, with the Sacramento Kings (six years) and the Portland Trail Blazers (four). In 2007, he rejoined Rick Adelman's staff at the Houston Rockets.
In May 2008, Turner was interviewed twice for the Phoenix Suns' head coaching position which had become vacant after Mike D'Antoni left. Ultimately, he was not hired.
In July 2009, Turner was interviewed for the vacant Minnesota Timberwolves head coaching position. Turner, along with Mark Jackson and Los Angeles Lakers assistant Kurt Rambis, was one of three finalists vying for the job, but Rambis was the Wolves' ultimate choice.
In May 2010, Turner was interviewed for both the Philadelphia 76ers' and the Chicago Bulls' vacant head coaching positions. They were eventually taken by Doug Collins and Tom Thibodeau, respectively. In June 2010, Turner was granted permission by the Rockets to talk to the L.A. Clippers about its vacant head coaching job.
In July 2011, Turner was interviewed for a defensive coordinator position for the Phoenix Suns along with the Milwaukee Bucks' coordinator Jim Boylan, the San Antonio Spurs' coordinator Don Newman, and current Golden State Warriors' coordinator Pete Myers. Turner signed a two-year contract, becoming the fifth assistant head coach for the Suns along with Bill Cartwright, Dan Majerle, Igor Kokoškov, and Noel Gillespie.
In July 2012, Turner was interviewed for the Portland Trail Blazers' vacant head coach position. He was one of the final four candidates, competing against Terry Stotts, Steve Clifford, and then-interim coach Kaleb Canales. Ultimately, he was not hired for the position.
