So if the opposing quarterback isn't going to struggle in the rain, why do I think it gives us an advantage? Simply because the weather will determine which plays Josh McDaniels and Tom Brady have to choose from. The plays which will be part of today's weather effected game plan are the plays which bring the team the most success. So far this season the Patriots have yet to be "beaten" by another team. Yes, the Patriots lost 4 games, but anyone who watched the games saw the team play to lose. When you play in the NFL and you have a game that consists of poor play calling, poor execution and poor ball security, you aren't usually going to walk away victorious.
I've already established that I believe the weather will have a positive influence on the play calling today. I also believe the weather will improve the Patriots' ball security. The reason I think ball security may improve for the Patriots in the rain is because they will be focusing on it. Other than a few fluke turnovers, most of the time they seem to be caused by players being lethargic. A home playoff game in the rain combined with Belichick's benching of Ridley earlier in the season will surely prevent any laziness from kicking in.
