Obviously this has nothing to do with the Green Bay Packers, but the NFL has been defined in part by Al Davis for so long that his death changes the entire league in a way. Via the SB Nation story stream, a quote from Raiders beat writer Tim Kawakami:

Al Davis attended Sunday's game. The last few years were a testament to his will. His body said he shouldn't work. But he worked. Big-picture: This loss is incalculable. The Raiders without Al Davis? Impossible to conceive of.
