The NFL free agency "legal tampering" period is officially underway, so we should see news and rumors start to trickle in. I keep seeing a lot of questions about who I think the Jaguars would be targeting in free agency and some of the names I bring up or positions I bring up, people might say "well you can get that in the draft" or something like that. In reality, all you have to do is just look at the Jaguars depth chart to see what they will likely aggressively target in free agency.
I'm going list the Jaguars depth chart, and just look where the holes are.
QB: Blake Bortles, Chad Henne, Brandon Allen
RB: Chris Ivory, TJ Yeldon, Corey Grant, Daryl Richardson, Bronson Hill
TE: Marcedes Lewis, Neal Sterling, Ben Koyack, Alex Ellis
LT: Branden Albert
LG: Chris Reed, Tyler Shatley
C: Brandon Linder, Luke Bowanko
RG: AJ Cann, Jeremiah Poutasi
RT: Jermey Parnell, Josh Wells
WR: Allen Robinson, Allen Hurns, Marqise Lee, Rashad Greene, Arrellious Benn
For me, the clear "holes" on the offensive side of the football in regards to free agency is the left guard position. Sure, they have guys who have started there, as necessity, but no one who can really be looked at as a long term option. It's also possible the team finds someone to play right guard and flip Cann back to left guard. It's also still possible they could look at a center and kick Linder back to guard. Outside of one of the guard positions, the other big hole is fullback if they plan to use one and the tight end position in my opinion is very weak.
RDE: Yannick Ngakoue, Dante Fowler, Jr., Chris Smith
NT: Abry Jones, Roy Miller (?), Louis Nix
UT: Malik Jackson, Sheldon Day, Michael Bennett
LDE: Jonathan Woodard
LCB: Jalen Ramsey
NCB: Aaron Colvin, Josh Johnson
LB: Paul Posluszny, Telvin Smith, Myles Jack, Dan Skuta, Marcus Rush, Hayes Pullard
FS: Tashaun Gipson, Peyton Thompson
SS: James Sample, Jarrod Wilson
On the defensive side of the ball, the clear hole is at the cornerback position and at the strongside end position. The team currently has no starter opposite of Ramsey, as it's pretty clear by now that Colvin and Johnson are viewed as inside corners. If the team's defensive scheme stays the same or moves to a more traditional 4-3, they still have the same problem; the only strongside end on the roster is a guy who was a 7th round pick who spent the season on injured reserve with an Achilles injury. The team still needs a bigger end for base downs, else teams will just run right over them.
Looking at this, you can see why I made the argument that offensive line is not the biggest need. They can get by with what they have if they absolutely have to, but as it stands the team would struggle to field a starting caliber defensive line and defensive backfield. The absolutely need to fill the hole at defensive end and at cornerback, before anything else.
