The Nets were the first team in NBA history to be five games above .500 on the road while being five games below .500 at home. Nets players did not have the crowd behind them at the Izod Center, because fans stayed away in droves.
It was common for some opponents to have more vocal rooters than the home Nets. The Knicks always have fans when they come to Jersey. Boston, Cleveland, Orlando, and Philadelphia also had vocal supporters when they were visiting.
Nets' ownership is attempting to build an arena in Brooklyn, and it is expected to be completed within three years. In the meantime, they have alienated much of their existing fan base.
The Nets' marketing team did a fantastic job drumming up interest with half-priced tickets and other special promotions, yet the Nets had the sixth-lowest attendance in the league.
For a lame-duck team that was not going to contend, I don't think they could have expected better, but it's still not a good situation.
Of course, trading Vince Carter for a popular player (Marcus Camby? Tracy McGrady?) could change everything.
