Mavs adding former Portland interim coach

Former Portland Trail Blazers interim coach Kaleb Canales will join the Dallas Mavericks as an assistant coach, replacing Jim O'Brien on Rick Carlisle's staff.

O'Brien, who had a 303-327 record as a head coach for the Boston Celtics, Philadelphia 76ers and Indiana Pacers, informed Carlisle on April 16 that he planned to retire after spending one season with the Mavs.

"Jim said he loved working in the Mavs organization, but being away from family made his decision easy," Carlisle said in an email. "I consider Jim O'Brien a great basketball man of high integrity and thank him for everything he taught me, my staff and our players this past season. We are fortunate that Kaleb Canales became available and had interest in joining the Mavs organization. Kaleb has worked for the Portland Trail Blazers organization in multiple capacities for the last 9 years, and brings great knowledge, enthusiasm and work ethic to the Mavs. He will join Monte Mathis and Tony Brown on the bench and take over in Coach O'Brien's capacity of coordinating our offense."

Canales was a finalist for Portland’s head coaching position after the Blazers went 8-15 when he filled in following Nate McMillan’s firing in 2012. The Blazers hired former Mavs assistant Terry Stotts, and Canales remained in Portland as the defensive coordinator on Stotts’ staff.

The 34-year-old Canales is a Texas-Arlington alum who worked his way up the ranks in Portland after being hired as a video intern in 2004.

"I'm very grateful to Paul Allen and Bert Kolde for the opportunity to work with a first class organization for the past nine seasons," Canales said in a statement.

"At this time, I am excited to have the opportunity to join the Dallas Mavericks. I treasure the relationships I built with the players, staff and fans here in Portland and also want to thank Neil Olshey and Terry Stotts for the opportunity to remain with the club this past season."

Canales' departure from Portland for Dallas was originally reported by The Oregonian.
