Other food for thought, and this may have already been said and I've missed it:
The stalking horse could pertain to agents. Just how, though, could be more convoluted than JFK's murder, but it makes as much, or more, sense than Gruden or VC. Sssterry mentioned the Beave, and he could be right. The Beave has operated under full anonymity and has taken all measures to preclude his identity from being known. This, in turn, begs the question, who is the Beave? Not what's his name and who does he play golf and drink scotch with, but is he a paid informant, or is he neck deep in the interwoven webs of Ergen and his mission?
