IMO, there are only 2 things wrong with the fan participation:
1) The Husker Power Chant - we all agree this is a ridiculous stance taken by corporate wonks who don't want to offend anyone.
2) The stream of people leaving when the clock goes under 4 minutes.
Beyond that, I had no issues with the fans yesterday. They cheered, got loud a few times when it was warranted...heck, those that remained did what they could to extol a defensive stop when we got it down to 6 with under 4 minutes to go. At a certain point, the product on the floor has to reward the cheers and outside of 1 magical run 2 years ago, it hasn't done that in many, many years.
I kind of liken it to the chicken and the egg story - some believe the chicken (fans) come first, I believe the egg (results/wins) come first. We saw what it could be like 2 years ago - give the fans wins and PBA can be a really loud, tough place to play. Until then, it will continue to be inconsistent at best.
