Littlefield: The Perfect Pats

Looking ahead to the big game in Foxborough on Sunday, the forecast is frigid. Expect a high of only 16 degrees, with the wind chilling that down into single digits at times.

Still, the New England Patriots are red hot — 17 and 0 this season — going into the A-F-C Championship contest against the San Diego Chargers.

WBUR'S sports commentator Bill Littlefield is anticipating an 18th consecutive victory for the Pats.
