The Jacksonville Jaguars defense ranks last in most the league's totals in the first three weeks of the season. Allowing 39.7 points, 466 yards, 306 passing yards, and 160 rushing yards per game is bad. These all rank last in the league. Head Coach Gus Bradley, a defensive mastermind, has been disappointed with the defensive performance that was supposed to be improved and considered to be force to reckon with, like their first week first half performance against the Philadelphia Eagles. The Jaguars have been awful on defense ever since and they made a total of six moves, most of which focus on improving their defense. The moves are as followed:

Re-signed Safety Sherrod Martin.

Signed Linebacker Jeremiah George.

Signed Tight End Nic Jacobs.

Waived Wide Receiver Kerry Taylor.

Waived/injured Safety Chris Prosinski.

Waived Tight End Marcel Jensen.

Martin, former 2009 second round pick of the Carolina Panthers, spent time with the Jaguars in the 2014 preseason for Jacksonville fighting for one of the spots on the roster, even for the starting safety spot, but lost out and was cut on the 53-player roster limit. With Prosinski going down with an elbow injury, Sherrod Martin hopes to make an impact on a very disappointing start by the secondary. 

Linebacker Jeremiah George was a 2014 fifth round selection of the New York Jets from Iowa State that was on their practice squad after the preseason. The Jaguars Linebacker core has been overshooting gaps and missing tackles so far this season and Jeremiah George gives the Jags more depth and solid, smart play from the linebacker position.

Tight end Nic Jacobs, former LSU-transfer to McNeese State un-drafted Costless Agent, spent time with the New Orleans Saints in the preseason and their practice squad. He looks to help a tight end position that looks to get receiving tight end Clay Harbor back along with blocking tight end Mickey Shuler and bring balance to the position, with Marcedes Lewis nursing a groin injury and won't likely be back until after their bye in Week 11. 

The Jaguars need something to go their way for their next game against the San Diego Chargers, being a 14-point underdog Sunday. They look to have rookie quarterback Blake Bortles make an impact immediately, but their defense needs to help him make the game close, as well. The organization and their fans are excited to see the rookie debut, but they also want to keep the game competitive and in their reach for the entire game. It all starts with their defense and Gus Bradley has attempted to address that with these transactions and we'll see if they pay off Sunday when they travel to Qualcomm Stadium.
