Warriors pregame: Kings guard Seth Curry (sprained right ankle) is listed as doubtful for Saturday night's face-off against his big brother, Stephen, and the Warriors. Meantime, Kings coach George Karl made interesting comments about the Warriors when asked about Golden State's balance. Warriors interim coach Luke Walton's response: I don't know what fake our bigs means. In other news, Bogut (concussion) will go through a "contact workout" Sunday, and if he comes out of OK, he could be available for Monday's game against the Pistons.
