Inside the matchup: Patriots at Jaguars – Extra Points – Boston.com

Injuries have hurt the Jaguars’ defense, which has talented players but overall has struggled this season. They give up an average of 27.4 points per game, which is fourth worst in the NFL. They’ve struggled defending the run, giving up a league-high 148 yards per game. A big reason for this appears to be the lack of gap discipline with the defenders, particularly on the backside of the formation. The backside contain defenders have been far too undisciplined at times, leaving gaping running lanes, which cost them on a few occasions last week against the Miami Dolphins.
