Either the Bears are going to win in a nail-biter, or the more likely outcome, the Colts will win by blow out. If the Colts establish even a hint of a running game then Manning wil be free to do what he does best, throwing short accurate passes. As for Rex, i don't think he will be a huge factor in this game. I don't think a good or bad Rex will show, just the "Don't F@#$ up and keep it simple" Rex will show. However if bad rex does show, then its going to increase the score of the blowout.
