...is a factor for both teams.
Experience in it does help, but technique in holding a ball can overcome a lack of experience. It's something a player can adjust to as he acclimates to the game conditions. It's not the "Ice Bowl" so we can forget trying to handicap the weather as a significant factor in the game.
The only players who will not like the weather is the kickers. The ball has a tendency to feel "dead" and kicks like a frozen rock in cold weather. With the fact that you may get on the field only two or three times this game and one of the appearances may be for the game it's not ideal.
Snow on the field is also miserable for trying to hold your plant foot in the ground. The Giants play on FieldTurf with polypro/polyethylene fibre combined with rubber and sand.
I've never had personal experience with it myself, but it sounds like a good artificial field that would drain moisture away and stay supple providing excellent traction as long as there isn't too much snow.
Last but not least the kicker has difficulty staying warm so I don't think a cold day is conducive to a long kick. Given that Feeley is facing off Cundiff, if it's cold with snow on the ground, I wouldn't give Cundiff anything more than a 40 yarder to try.
