The National Football League has a different structure, as all games require over-the-air broadcast and the league and teams are generally loathe to use only a local cable broadcaster to distribute preseason and team programming. An anti-siphoning policy is also used by the league in order for local stations to bid for "Monday Night Football" games for over-the-air distribution when local teams play. Most of the league's teams partner with a local station or regional network of stations, which distributes team programming and weekly analysis shows featuring a team's head coach, with those stations allowed to market as a team's 'official station', often tied into preseason rights. In a lesser arrangement, Major League Baseball teams often name a local broadcast station their official weather forecasting partner and allow them to market as such.
