I agree, you can't blame Ardley for Barclay losing his head. But you can blame Ardley for starting with three inexperienced centre backs. It was pointed out on here before that game that that was risky, and also by Charlie and Stall on radio Notts. Of course he can't have foreseen what would happen, but that's exactly the kind of thing young pros do. Just like Schofield's brain fart against Carlisle.
