Actually...the Chargers just suck! They fired a good coach because he got them to the AFC Championship and LT hasn't been the same since going "Thug" in the loss. They got robbed in that game but ultimately it will help them with a better draft pick. They weren't going anywhere even with another win. You won't find another city with sports (and fans) as weak as San Diego.
Trust me, you can. I used to live in Atlanta. Those are some horrible fans down there. The Hawks and Falcons have been dreadful for years. The Braves were good for a while, but seem to be headed south as well.
I lived in the Bay Area, and Raiders fans are the most disgusting, rude and pathetic fans you'll meet. I hate the Raiders more than the Cowboys... and that's saying something. The Sharks and the Giants were good while I was there, but the 49ers and the Raiders had fallen off completely.
