Por que está dando problema no "add"?

JPanel c1 = new JPanel();
	c1.setLayout(new GridLayout(23,1));
	c1.add(nome1);
	c1.add(time1);
	
	JPanel c2 = new JPanel();
	c2.setLayout(new GridLayout(23,1));
	c2.add(nome2);
	c2.add(time2);
	
	getContentPane().add(BorderLayout.WEST, c1);
	getContentPane().add(BorderLayout.EAST, c2);

	//configurarRede();

	setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	setSize(500, 500);
	setVisible(true);
}
