sure, every seat being full is cool, but we're actually seeing 90% of the seats occupied as it is, even though some of the talk on here makes you think it's a massive problem and half the stadium is empty or something. This article explains why it doesn't matter. Also, apparently the NFL is being forced to drop its blackout rule. If you ask me, it's about 30 years obsolete anyway. TV is the reason the NFL is what it is, and the blackout rule is a dinosaur and one of the few things the NFL has been kind of foolish about. It nearly killed the Cardinals in Arizona in the 90s when they sucked and the team had few ways to attract more fans because they were so often not on TV due to the rule.
