I just spotted this when Microsoft was the featured link for Wikipedia, and I clicked on Paul Allen’s link, the dact that he owns bothe the NFL Seattle Seahawks and the NBA Portland TrailBlazers. I thought the NFL prohibited owners from owning teams in other sports as well, IIRC, Wayne Huizenga had to give up his stake in the Dolphins in order to become owner of the Marlins and/or Panthers. Does that only apply to teams that share a media market with an NFL team? If not, did the NFL waive this for Allen? If so, why would they make him an exception?
(Wikipedia entries on Allen and on the two teams failed to yield an answer.)
