So far, however, defense has been as big an issue for the Jaguars as their offense has been.
While some might point to the key injuries the Jaguars have had to deal with so far this season, most notable among them defensive captain Daryl Smith, the poor play along the defensive line has been what is truly preventing this defense from returning to its 2011 form.
Through the Jaguars first three games, the defense has only accounted for two sacks. Neither of those sacks has come from the defensive end position.
The lack of pressure the Jaguars have been getting on the opposing quarterback has led to coverage breakdowns in the secondary and issues with being able to get off of the field when they get their opponent into third down situations.
Both Jaguars starting defensive ends, Jeremy Mincey and Andre Branch, have got to do a better job getting to the quarterback, and as we saw yesterday, when they get there they have to wrap him up. While the Jaguars were able to hit Andrew Luck, they were never able to bring him to the ground and allowed him to convert some key third downs with his feet.
The poor defensive line play has also led to a massive drop off in production from the Jaguars run defense. The Jaguars are allowing opponents an average of 154.3 yards per game on the ground, which ranks towards the bottom of the league.
While stopping the run is a total team effort, the Jaguars defensive line needs to do a better job winning the line of scrimmage and bottling up opposing runners.
It is too early to press the panic button on the defensive side of the ball for the Jaguars, but if they do not start getting better play from their defensive lineman it could get worse.
