“If it happens again, then things have to change. But those are three isolated incidents over three years, so it is not as though it is happening every week.”
If England bat okay in the first innings of the next Test but are then skittled again in the second, is that an isolated incident? Is it isolated by a single instance of competence?
Is ‘every week’ the frequency with which things have to go wrong in order for there to be a problem?
