Agreed. Since the introduction of the helmet, we are seeing far more cases of batsmen being struck because they are taking their eye off the ball. Khawaja showed us all precisely what NOT to do when confronted by a short ball that suddenly gets big.People hate hearing this, but with almost zero exceptions a batsman who is hit in the head played the ball badly and/or took his eyes off it.
Khawaja today, Smith at Lords, any number of times Langer was hit or Pucovski more recently, and Hughes in 2014.
It is a symptom of an error, and being hit repeatedly is a symptom of a poor technique.
There are very few examples of pure bad luck.
I was hit twice when I was batting, and both times it was 100% my fault for taking my eye off the ball and hoping it would miss me.
Ian Chappell told a funny story, I think the bowler was Lennie Pascoe, the batsman was Viv Richards. Pascoe peppered Viv with a number of short balls and umpire Max O'Connell stepped in to warn Pascoe about excessive short balls. Next thing you hear Viv at the strikers end, "No, don't stop him Max!!!!"
