EL SEGUNDO -- After nursing soreness in his left knee in recent days, Lakers guard D'Angelo Russell seemingly checked all the boxes to return to the lineup. He completed pregame warmups without limping. The Lakers' training staff determined he felt fine enough to play. So did Russell.But in the Lakers' 118-110 loss to the Chicago Bulls on Sunday at Staples Center, Russell posted only eight points by mostly relying on jump shots and 3-pointers.
