The East Valley Tribune (Matt Paulson) reports: The Suns began the interview process in their search for assistant coaches on Tuesday, bringing in former Chicago Bulls head coach Bill Cartwright. Buck Williams, an ex-teammate of new coach Terry Porter, will interview today. One of the Suns’ top priorities in filling out Porter’s staff is hiring a former All-Star big man known for being strong defensively and a good rebounder — a coach who can help bring along Amaré Stoudemire’s development… Also on the Suns’ list are Alvin Gentry and Jay Humphries, holdovers from former coach Mike D’Antoni’s staff. Suns TV color analysts Dan Majerle, who played with Porter in Miami, and Eddie Johnson are expected to interview, along with former player Jeff Hornacek.
