Mentioned above but, the biggest problem with crowd noise at Gillette is..... the crowd. I legitimately had people behind me TEXT security on us for standing up while the Pats were in redzone in a game a few years ago... you can do this anonymously now. I'm sure everyone on this board is a great fan but our fans kind of suck in terms of gameday. Sure, we fill the stadium and there are alot of good ones, but I see a ton of people sitting the entire game/leaving early/texting on their phone the entire time.
Not gonna change my mind on that one.
All of that said, I think the stadium renovations seems like a solid idea.
