Bears’ keys to victory: The last time QB Mitchell Trubisky saw the field, he had a record-setting day in Chicago’s 48-10 win over the Buccaneers, throwing for 354 yards and six touchdowns. Considering the Dolphins’ inability to pressure passers, Trubisky should be able to complete plenty of short passes to his receivers. Also, RB Tarik Cohen’s game-breaking speed should be an effective weapon for Chicago. The Bears defense has been even more outstanding. It ranks among the league leaders in yards allowed per game (294.8).

Dolphins’ keys to victory: QB Ryan Tannehill will need to take care of the football — he turned it over twice, and both mistakes were returned for TDs in the second half of Miami’s 27-17 loss to the Bengals in Week 5. One was an interception that bounced off TE Durham Smythe. The other was a fumble. The defense is giving up nearly 400 yards per game, though it has managed to limit the points damage to a relatively low 23.4 pergame average.

Matchup to watch: Bears’ front seven vs. Dolphins’ offensive line. Injuries have wracked the Dolphins’ O-line; C Daniel Kilgore and G Josh Sitton are both out for the season. So it will be interesting to see whether they can block LB Khalil Mack and the Bears’ tough defensive front.

Who wins? The Dolphins have a ton of injuries, and the Bears defense is one of the best in the NFL. Also, the Bears offense should be able to move the ball against the Dolphins defense, which performed poorly in the second half against the Bengals.

Bears, 27-17 Bears
