lot of nervous energy which only doubled when they were down in game 2 of the Spurs series (Will Barton got a lot of boos that game). After Murray went off in the 4th of that game it has just been really loud. Everyone getting up and yelling for every shot and booing every call that is at all questionable.
You could see Pop on the court stomping and yelling at Aldridge and Mills to foul at the end of game 7. There was no way any of them were going to hear him, it was simply too loud. It has been the best atmosphere I have ever been involved in at a Nuggets game and I have been to some of the few games that the Nuggets did well in (I was there when we made the WCF in 2008-2009 and also when we upset the Spurs in 94-95, not a lot of winning playoff history in the franchise since the '80s other than those).
