I don't put much stock in the lack of an "interim" label. No NBA coach lasts forever. So they are all interim. Why cut the guys clout unnecessarily by adding the label? There will be more coaches to pick from in the off-season, so they want to wait and do the search then. Right now, the players have to take him seriously. He is the coach, and still the GM. If they label him "interim" it sends a signal he's not even going to stay as GM.
