Allen still easily NFL's richest owner

Seahawks owner Paul Allen's estimated net worth in the late 1990s made him wealthy enough, in theory, to purchase every NFL franchise and quite a few in other leagues.

His fortune had dwindled from an estimated $40 billion back then to an estimated $10.5 billion in 2009, but that figure improved to $13.5 billion in the latest Forbes magazine rankings.

The chart breaks down where Allen has stood in the rankings since 2007.

Rams minority owner Stan Kroenke ranks 342nd at an estimated $2.9 billion. The Dolphins' owner, Stephen Ross, ranks 277th at $3.4 billion.
