James Dolan’s biggest gripe with the league, according to several sources around the NBA and familiar with Dolan, has been with the league’s revenue sharing system. The NBA allocates money from the teams in its biggest markets and gives to those in the smallest as a way of trying to create an even financial playing field. Ultimately, that puts the financial burden on just a handful of franchises, with the Knicks chief among them. “Dolan hates the idea of giving money on revenue sharing,” one former NBA owner said. “He’s been totally against it from the beginning.”
