FILE - In this Jan. 26, 2010 file photo, Ed Mangan, the NFL field director, talks to the media at Sun Life Stadium in Miami. Perhaps the only people connected to February’s Super Bowl who aren’t worried about the weather are the National Football League’s groundskeeping staff. That’s because they’re used to dealing with the elements _ and improvising when they have to. Mangan has worked at more than 20 Super Bowls. (AP Photo/J Pat Carter, File)
