The Oregonian reported that Stotts, the Mavs' offensive coordinator, interviewed with new Portland general manager Neil Olshey on Tuesday and is likely to get a second interview.
Stotts is one of several assistant coaches who have reportedly interviewed or been in contact with the Trail Blazers, including Golden State's Michael Malone, Chicago's Adrian Griffin, Phoenix's Elston Turner, Atlanta's Lester Connor, Indiana's Brian Shaw, Memphis' David Joerger, San Antonio's Mike Budenholzer, former New York assistant Phil Weber and ex-Orlando assistants Patrick Ewing and Steve Clifford.
Stotts, 54, has a 114-168 record as a head coach, having spent parts of four seasons at the helm of the Atlanta Hawks and Milwaukee Bucks. His best season came in 2005-06, when the Bucks went 40-42 and lost in the first round of the playoffs.
Stotts joined the Mavericks as an assistant soon after coach Rick Carlisle was hired in 2008.
