I know this may bother a number of you here, but I do not harbor much if any hate for the Raiders.
Primary reason is that I grew up outside SF most of my life, so a real life Raider fan I have never met (two sorta Raider fans....but not a true black and silver fanatic). So that aspect of the hatred I haven't experienced. On the flipside I have known many a NY Giants fan, and my hatred for them is greater than the average 49er fan if that's even possible, lol.
I submit that the league could actually benefit from a good Raiders team. They are a historic franchise from the '70s TV age of the NFL, and the fact that they are a Bay Area rival is pretty cool. There have been two opportunities for a 49ers/Raiders super bowl ('83 and '02)....
The organization is a mess from top down, which is why they will continue to have problems. They're easily the worst run team in the league, without question. Not sure if Davis, the son is the answer. The team might need to be sold to someone who could do it right.
I'm not hoping for a return to glory winning super bowls but seeing them come out of the cellar would be good for the NFL, IMHO.
