No, cold weather is good for us. Manning's noodle arm dies in that type of weather. Remember how ineffective he was against NE in the regular season game?
^^What these guys said. Manning's stats in bad weather games speak for themself. If it's windy (come on, it's MetLife in February) then that will be a distinct advantage for us.
This is from weather.com for Feb 02, 2014.
In another two weeks or so, we should have a better idea. Hopefully we get a freakish weather day, a couple of days ago, it was like 53 and sunny here. Almost warm.
