I don’t think that an undefeated NFL team has ever replaced their starting quarterback so early in the season, but the Bears didn’t bring in Nick Foles for no reason. Foles replaced Mitch Tribusky last week and sparked a comeback win against the Falcons, and it's now his starting job to lose. The Colts will be a tougher matchup for the Bears, however, as Indianapolis wants to run the ball and be physical as they rank sixth in the NFL by running the ball 48.4% of the time. The Bears defense, on the other hand, rank 26th in the league against the run, allowing 119 yards per game and five yards per carry. Jonathan Taylor has a good chance of having his second 100-yard rushing game of the season here. With Foles at quarterback the Bears will probably look to throw the ball more often, but the Colts defense is pretty good against the pass, allowing opposing quarterbacks a lowly 62.6 completion percentage, 132 yards per game (ranks first overall) and a 64 QB rating (ranks first overall). Both teams have a defensive Yards Per Point that’s either average or better, so this could also be a low scoring game in Chicago.
