Arena football is different. It's the kind of sport where a fan reaches out of the seats to bodily prevent an opposing player from returning a kickoff. And more tellingly, it's the kind of sport where the home team's players then go over to congratulate the fan for interfering with play.
The Jacksonville fan wasn't ejected, but the refs huddled and decided to give Georgia the ball on the 20. I'm not sure what penalty covers this situation — perhaps illegal use of the fans? (Oh, that's awful. Sorry, it's comedy week.) Seattle's 12th man looks like a giant pussy now, as Jacksonville won the game and advances to Arenabowl XXIV.
