The Chicago forecast has rain in it every day from tomorrow until the game. There could be some sloppy conditions to deal with.
Good thing we can run the horsefeathers out of the ball, and I thought the D played alright against the run in Carolina. I saw some of Minnesota week 1 and Carson was playing on a knife's edge a bit. Given that the game will be outside and in possibly imperfect conditions, I think the Bears roll.
