Having been on the receiving end of it as a Wire, as I'm sure most of us have, Cas' main responsibility is to ensure the survival of the club and the odd Wembley appearance isn't going to change that I'm afraid, so the tangible assets are all fair game.
Of course, at the risk of sounding condescending, as one door closes another opens. When Andy Greg left us most people of a P&B persuasion thought the oceans would boil and the planet would fall off it's axis, then along came a lovely fella called Keith Holden who could also play a bit and we all moved on.
The fact Keith sufferred a career-ending injury all too soon is another reason on top of the 180,000 others we know of as to why Cas have done the right thing to cash in their chips.
