Why? Some people can't afford it, others live to far away (such as myself).
But when the players and the media talk about the crowd and how quiet they are, it is a shame.
You don't have to be there to hear how quiet it is. And I am sure that the season ticket holders that post on here are not the problem.
So don't be offended by it. Many folks who are non-season ticket holders who attend Pats games have come away with similar impressions of Gillette and the crowd as a whole. It is something that shouldn't be dismissed, especially if you are there every week.
The stadium design may reduce the overall noise, but it doesn't cause silence. Again, I will point out how loud the crowd was in week two against the Chargers, that stadium was rocking. The stadium has not changed, so why can't it be that loud every week?
