Don't delete threads because you're afraid of death. It's a valid question, the one about boxing post-arum/king.
They will soon die, I suppose that's the point. It's hard not to forecast that GBP will gain an even greater share once Arum kicks off. Top Rank is too big and too well run of an organization to dissipate once the boss is gone, but it is yet to be seen if DuBoef (or whoever else is selected to head the company) will have the same sort of acumen as the Bobfather. Don King is already effectively irrelevant, with the notable exception of Valuev.
