FILE - In this Dec. 31, 1967 file photo, players spill in all directions as a fumble occurs in the third period of the National Football League Championship game, known as "The Ice Bowl" between the Dallas Cowboys and the Green Bay Packers at Lambeau Field, in Green Bay, Wisc. Dallas quarterback Don Meredith (white jersey, #17) fumbles and Herb Adderly of the Packers (#26, partially hidden) reaches to recover it in the game played in sub-zero temperatures. Instead of shrinking from the possibility that football?s ultimate championship could be played in a blizzard, organizers of the first outdoor, cold-climate Super Bowl, Feb. 2, 2014, in East Rutherford, N.J., have decided to embrace the snow as the game?s unofficial theme.
