Maybe using Daniel Vettori as a coach isn't such a bad idea, I don't think he was a natural test spinner, but knew the game and knew his own game and became a high quality spinner. We need someone who can get the best out of what is pretty limited natural talent. Both Rashid and Ali currently look like fifth bowlers in English conditions, when they can offer a couple of short spells, get decent revolutions on the ball so get the odd wicket, but not put together a long spell for few runs.
