The folks who scheduled the Green Bay-Chicago matchup for "Monday Night Football" in late December knew it would be numbingly cold. Weather.com is forecasting a kickoff temperature between 7 and 12 degrees, with 16-mile per hour westerly winds creating a wind chill of -6 to -12. For last year's game on Dec. 23, the kickoff temperature was 16 degrees, and the wind chill was -2, with wind gusts of 40 miles per hour.
