Have Proteas JP and Miller lost their mojo?

Don't touch Russell Domingo on his players. Even those who have gone six and nine, completed one-day and Test innings without scoring 50 or been the only man in a squad not to crack the selection nod in a series.Those players are JP Duminy and David Miller, both among the finest in the game.Asked on Wednesday if he was concerned about their missing mojo ahead of the Twenty20s South Africa will play against England at Newlands and the Wanderers on Friday and Sunday, Domingo came out swinging.
