it was the niners fans whose violence ended the traditional bay area preseason matchup. i know because I was there. Also never forget SF fan brian stow, beaten to crap by dodgers fans for no good reason. philly, well, i suppose they are famous, regardless of which sportI’m not into sports but I think Raiders fans and Eagles fans are probably considered the worst fans in America
also i suppose we are all better than euro football fans, where watching a game in person is fatal FAR more often than it should be
