So the Spirits were one of the ABA teams that did not get absorbed by the NBA. But this is crazy (from Wikipedia):
But the owners of the Spirits, the brothers Ozzie and Dan Silna, struck a prescient deal to acquire future television money from the teams that joined the NBA, a one-seventh share from each franchise, in perpetuity. With network TV deals becoming more and more lucrative, the deal has made the Silnas wealthy, earning them $186 million as of 2008, according to the Cleveland Plain Dealer, and $255 million as of 2012 according to the New York Times.[1] (The NBA nearly succeeded in buying out the Silnas in 1982 by offering $5 million over eight years, but negotiations stalled when the siblings demanded $8 million over five.) On June 27, 2007, it was extended for another eight years, ensuring another $100 million-plus windfall for the Silnas. Presently, the Silnas receive $14.57 million a year, despite being owners of a team that hasn't played one minute of basketball in 35 years.[2]
