Jousting with reporters in press conferences is apparently not the lone source of pushback these days from under-fire guard Russell Westbrook. There has been no shortage of defiance behind the scenes, I’m told, when coaches and teammates have tried to broach changes in role or approach with the former MVP. For all the obvious complexities involved in trying to move Westbrook when he’s owed a whopping $47 million next season at age 34, one league source described the idea of bringing him back next season as “impossible” based on current tension levels. The question then becomes: If the Lakers can’t construct a palatable trade, do they try to just buy Westbrook out? Or waive and stretch him?
