When it comes down to it somebody received those e mails and why are only Gruden's released? Could Kroenke and Snyder both be implicated in this and that's why everything else is kept under wraps?
it's an old boys club - look at the way coaches have been on a hire/fire merry-go-round for years - it's a club and has been for years (only really starting to open up somewhat with some of these younger guys but even then there's quite a nepotism tree going on) - a lot of people are likely to have been complicit in similar conversations even if they haven't contributed...
there's no way snyder's not implicated in this given that this all centres around bruce allen and washington throughout his tenure (and the fact that the aural investigation with no written report forced him to step down from day-to-day operations) - ironically mark davis is probably one of the few owners not implicated in this (because he had to be sent all the correspondence etc. in the first place)
