12 NBA owners make "The Forbes 400 List" for the richest people in America, all have a net worth over $1.45B

Until the league makes team financials public, we won't be able to better correlate an owners wealth to how much their team makes and how much they spend on their team. However, it is worth nothing that one of the main complaints of owners during the lockout is the decline in franchise valuations. Michael Heisley bought the Grizzlies for $160 million dollars, and the team is roughly valued at $257. Heisley is upset that he can not find a buyer willing to pay $300 for only a 70% stake in the team, which would be a substantial profit based on the purchase price (of course there is the losses the team has incurred over the years). This case is probably not a sole incident among owners complaining of losing money. Is it that the owners are losing too much money, or not making enough money?
