Graeme Smith and Colin Cowdrey already had the injuries, so they could do that. It is different that injuring yourself deliberately. They knew they were going to miss the next few games with injury.
People have died by getting hit in the heart/throat area but you would put the team ahead of your life I presume.
Moeen had 6 balls to 'manufacture' a single. I have not sen the highlights yet, but I would guess one ball could have been worked for a single.
Cook, Bell, Robson, Plunkett all played bad shots on the first night and Ballance missed a straight one, yet you blame Anderson???
If he had done that in the morning session and England had been bowled out before lunch, you wouldn't be saying he should wear one, so why now?
