They obviously needn't be and if it were the last father and son pair of encumbents I'd say there was some sense I that. I don't see DB that way though his profile isn't high enough for that for me. Just my opinion though
I disagree with your point that if they cared only for their pockets they wouldn't be here. Their decision to be here in the case of DB will have rested purely on his take on things from a business optunity. Nothing else would have come into it. He isn't here to shake hands, make friends, or sponsor a football team unless that is what is needed to get his deal.
Yeah who knows, you might well be right.
If I was looking for somewhere to turn my 6, 7 or 10 mil into something a lot bigger, though, a football club would be very close to the bottom of my list. Land or no land.
