The potential for bad winter weather certainly would be even more of a help to their already-great defense. But I don't think the Bears play an offensive style that's all that favorable for playing in wind, cold or snow. They don't run the ball all that well, and they have been using the deep pass extensively so far this season. They are very capable of running the ball well, as they did last year with the same squad. I think they've gotten away from focusing on that aspect, partially in an effort to get Grossman developing, and partially out of ego once they realized they could throw. I bet they run a lot the rest of the year. The Bears have the third worse YPC in the NFL. They aren't running as much, true, but when they do run the ball, they aren't effective at all. Like I said, they haven't focused much on it this year, and I believe it was a combo of putting so much effort into developing Grossman and partially out of arrogance.
