Looks like the heated field will be ok, but there is a 20% chance of light snow during the game, could hit, melt, and be wet or hell, freeze and be slippery if the heated field does not win the battle.
Gametime, they say, will be 31 degrees, "feels like 24", and yes this will limit the passing game. Some QBs are OK, some are not. The grip on the ball, the touch. And many receivers are not able to adjust. Some can. What a difference a 30 yard dropped pass can make.
I do know Luck mostly throws a very catchable ball, soft touch, does not zing it every time like some, and that might be something to consider. But he is a dome QB in cold weather. Mahones, who knows, he is very talented but this is a cold weather game.
10mph winds, they say, at this point. Not too bad especially if it is not a cross wind, but goes end zone to end zone.
