"Watching Steve Smith against England last month, he’s stopped doing that big trigger movement, when he goes back and across his stumps before the ball is bowled. And now he says he’s batting better than ever! Joe Root is another one who’s played around with his pre-ball movements. Both seem to me to be more side-on at the point of contact than they were in the past. So what’s going on? And would you recommend that ‘normal’ players follow suit?
