green bay is 3-4 when temp is 6 degrees lower , not sure how aaron rodgers connects to that stat because that is in green bays history, so game time temp is forecast for a high of -3 and a low of -19 and that isn't even counting the wind chill. So sure maybe he has played well in cold weather but honestly i don't think any of these players have played a game in this cold of weather before, we are talking about ice bowl numbers
I would hate to smash a hand off a helmet in this weather but I wouldn't expect anything too different.
