Hey, it's a completely valid question. England focus their entire cricketing logic on the Ashes. "England vs West Indies is practice for the Ashes." "Oh, the T20 WC is just practice for the Ashes." "The T20 WC is a good warm-up for Flintoff when he comes back to the team".
England base their entire cricket towards the Ashes, but can almost never justify it.
