^ exactly. You have to invest in players, otherwise it's counter productive. What, we want him to average 45-50 batting at number 8? Who's ever done that?!
He could bat anywhere from 4-8. He's part of an England team who are building for the future and players like Moeen, Root, Stokes, Bairstow are the core of a team that;s only going to get better. And they're winning. He;s a selfless player doing a decent, but not spectacular job. Many with less ability have had decent test careers.
