It’s not that this comes from left field. “I’ve seen a steady growth in his confidence and being able to give his opinion, so I just feel it was a time to get a fresh voice. “I think he is a highly intelligent cricketer. He comes across as quiet, but in terms of his intelligence, he is right up there with some of the best young players in the country that I have spoken to,” he said.
