You remember two weeks ago, when we reported that in 2007, Forbes ranked the Oakland Raiders the fifth-least valuable team in the NFL? Well, the new numbers are out, and the Raiders are now officially the second-least valuable team, with only the Minnesota Vikings bringing up the rear. For God’s sake, the Miami Dolphins went 1-15 last year, and they’re the 13th most valuable team in the league. But don’t weep for Al Davis just yet. When Davis bought the team in 1966, he paid $180,000. When he sold just twenty percent of the team last year, he netted $150 million.
