I am going to say Colts.
However, if the Bears win, it will be because Hester runs back a couple for TD's or the Bears Defense outscores their offense.
However, if the Colts do win, imagine how many MORE commercials with Peyton Manning there will be...instead of every other commercial it will be every 2 out of 3. He may not be able to win the big game, but his agent is on fire.
