On Monday, the National Football League announced that players, coaches, and other team personnel can use social networks such as Twitter and Facebook during the season. However, they are prohibited from using social networks starting 90 minutes before a game, through the game, and until post-game interviews are complete.
The rules extend to people representing a player or coach, such as agents, friends and family, and even include the media covering the games.
Twitter has (had?) the potential to pour gasoline on the already very profitable fantasy football movement.
