I don't know, for me the crowds are no where near what they were back in the early 2000's. It's getting to the point where, from an entertainment standpoint, I prefer to watch the Celts on the road where at least the opposing crowd brings energy to the game. Games at the Garden tend to feel boring, and tonight was much of the same despite being a close out game. Even Gorman commented on it a couple of times.
If I wasn't a Celts fan or Heat fan, I wouldn't have watched it. Back in the early part of the decade we sounded a lot like the OKC crowds (check the videos at the beginning of the thread). Today, dare I say, we sound worse than staples.
I know the TV broadcast drowns out the noise to an extent, but they don't distort the video, and I see a full stadium sitting on their hand for the vast majority of the game. For some reason I don't think their blowing the roof off the place from their seats. Beyond killing the atmosphere of what should be great playoff basketball, I don't think any opposing teams are intimidated of playing in the Garden.
