Today he clocked Labuschagne with a very dangerous ball. In the WC he hit Amla and another Aussie bat with vicious deliveries.
This isn't happening by accident. It's a skill. As the panel of Warne, Botham etc concluded, it's because the ball chases the right hander. They might have added he has found the perfect head high ball length.
So no doubt his pace, movement off the pitch and length is pretty unique. The question is.....is it dangerous? And certainly without head protection it clearly is. Somebody could have been killed.
But even with head protection somebody could get hurt.....the thyroid for example. And of course concussion as with Amla. Odd how in the supposedly tough game of rugby the head is carefully protected...but head hunting is okay in the gentleman's game of cricket.
