While thats still incredibly expensive...beyond any blue collar salary's worth for a weekend event...I believe that the reason for any fall off the average boils down to this:
Tom Brady and the New England Patriots are back. Again. And the average sports fan is getting tired of it. One of my boys (who is die hard Redskins) has said he will not watch the SB with Brady and the Pats in it. I get tired of the whining about cheating and yada-yada but still. The point remains that its not very enthralling to watch Tom Brady win his 519th Super Bowl against a team with a backup QB.
