The Jacksonville Jaguars defense has been one of the biggest disappointments of the 2012 NFL season, going from a top six ranked unit in 2011 to one of the worst in the NFL in 2012. While the team has been without star linebacker Daryl Smith and an injured Clint Session, the majority of the defense that was so good in 2011 is still in tact.
The biggest problems on the defense, outside of lack of talent, is little mistakes that cause big problems and players just flat out not playing well. Former first-round pick Tyson Alualu was on the ground way too often against the Buffalo Bills last week and found himself on the ground quite a few times. Terrance Knighton, who's in a contract year, was also pushed around in the run game and didn't maintain his gaps.
The Bills ran the ball for well over 200 yards on Sunday and only felt the need to pass the ball 17 times in their blowout win. Going forward, the Jaguars defense is going to have to stop other teams from running the football or the defense will continue to be in for a long day.
