Not sure honestly how much any of this can be fixed unless theres better lighting or a video scoreboard for those videos pregame like someone mentioned. The atmosphere has been like this for years, even when they were winning. The fight song is fine, it sounds like a fight song.
I for one agree that the intro of the team should be changed, a wind up machine with Zombie Nation has run its course. That said we're there for the basketball team and as long as the team wins, and as fans we can get into the game curse/scream/hiss thats all I want. If something like that is lame to you, dont pay attention to it or drink an extra beer in the Gold Room or at Brion's or check out information online about the other team. The other stuff is just extras that isn't going to make a break someone willing to attend.
Homecoming is probably not going to be changed although opening night would be interesting and the opponent doesn't really matter. I just don't think basketball is a tailgating friendly sport because of the weather, and most people would rather hang out at Brion's or the Gold Room and call it a day.
