Paul Allen, owner of YOUR Portland Trail Blazers, clocks in at number 26 on the richest people in America list. And if you were to combine the Koch brothers (2), the Mars candy people (3), and the Walmart Waltons (4), he'd be in the top-20. Don't feel too bad for him though, he's the only one with a Super Bowl ring.
He may have some competition coming up. If/when Seattle gets their basketball team back, one of their minority owners is Steve Ballmer (#21). And I have no idea how to convert rubles, so I don't know how Comrade Nyetski measures up, except that he has spent a bung-load on a truly awful team.
