I'm a Raider fan who was born in LA, I'd rather have the Raiders close to where I call home now I'm the bay, but either way I'm still a fan. I hate San Antonio as a city and don't like the Spurs, but I'd disappointingly root for the San Antonio Raiders. I remember the LA Lambs, and I still look at them as the Raiders little brothers like the Clippers were to the Lakers. Times change, the clippers are looking like they're pushing towards the finals and the Rams just beat the absolute shit out of us. But the Rams returning to LA would be good, they are NFC WEST, so it makes more sense for them to be on the west coast. Sharing a stadium with division rival Chargers is the stupidest thing I've ever heard in my life. I don't have a real problem with sharing the Santa Clara stadium with the Niners, but I think every NFL team should have their own stadium. Except NY, fuck New York.
I doubt they pick up and leave after the season, I would expect some sort of announcement prior to the season start but ya never know, ya know?
