In the first paragraph of your post you were right on the money. However outside of QB and OL where exactly do you see our TANGIBLE advantage in personnel??. Quite the contrary, it looks to me that it is Chicago who has a number of "tangible personnel" advantages at RB, more explosive WRs, kick returners - DL, Pass rushers, LBs And in the area where we have the advantage QB - it isn't as large as it was last week.
When you consider all the "intangible" obstacles you mentioned in your first paragraph, and add the personnel issues, I can't believe there aren't more "mediots" who are picking the Bears. I'd feel real good about our chances on a good field with decent weather. All those obstacles and the bad weather makes me nervous. A few lucky bounces either way will decide this game.
