I went last season. Agree with the others that the real danger is outside the stadium. Some gang member told me I was wearing the wrong colors as I walking to the game. Turned to look at him, he threw up a gang sign, I realized we weren't talking about football, and kept walking. Luckily, was in a crowd of football fans. The parking lot was insane - saw many fights, most between gang member types (mexicans with red bandanas on their heads, etc).
Inside the stadium during the game was about normal. People talking smack at us, some guy poured a beer on my friend, a couple drunks tried to start a fight with us on the way out. But during the game, most of the fans were actually paying more attention to the Giants game (who were in the playoffs).
I'd say it's a bit more dangerous than other stadiums, but if you're used to going to road games, you'll know how to keep your head down, keep your mouth shut, keep moving all the time, don't try to smack back. You'll be okay.
