I think Wells started drinking his own bathwater after '99/'01 when he nailed Enright, Ling etc with late picks and thought he was some kind of oracle. Fortunately, in more recent years, he's been far more conventional.
Anyone who has met and spoken with him will know this just could not be further from the truth. He is one of the most humble and driven people you will ever meet. I have never met anyone who is less likely to get ahead of themselves or let arrogance about their own quality get in their way.
