JACKSONVILLE, Fla. -- A closer look at the positions the Jacksonville Jaguars could target at the NFL combine in Indianapolis:

Positions of need: Offensive line is the Jaguars’ top priority this offseason, and they are expected to address it in free agency and the draft. Both guard spots need upgrades, and it also wouldn’t hurt to add another tackle to push Jermey Parnell. Beefing up the edge rush is a priority, too. The Jaguars seem to have hit on defensive end Yannick Ngakoue, but there are still questions about defensive end Dante Fowler. Opponents don’t have to do anything special to combat the Jaguars’ pass rush, and that has to change. The defense hasn’t had a player reach double digits in sacks since Bobby McCray in 2007. The Jaguars also need a safety to complement Tashaun Gipson, more bodies at linebacker (middle linebacker Paul Posluszny turns 33 in October) and a pass-catching tight end who can create mismatches.

Five players the Jaguars could focus on at the combine:

Forrest Lamp (guard), Western Kentucky: He was a four-year starter at tackle in college but projects to move inside in the NFL. Lamp is listed at 6-foot-3, 296 pounds, so he’s a little light, but scouts like his toughness and nastiness. His size, however, raises questions about how he’ll hold up against bull rushes from interior defensive linemen in the NFL. One other concern from ESPN’s scouting report on Lamp: He doesn’t seem to have good instincts on tape. Still, he’s regarded as one of the top two guards in the draft, especially because of his athleticism.

Dan Feeney (guard), Indiana: According to ESPN’s scouting report, he doesn’t have ideal lateral agility and doesn’t overpower people in the run game. However, he has attributes offensive line coaches love: He’s a grinder, he plays with an edge, and on tape he never seems to get caught off guard by stunts or twists (an area in which the Jaguars struggled last season). How about this stat, too: Feeney started 37 games at right guard for the Hoosiers and allowed just one sack. He's a player the Jaguars could target in the second round.

Solomon Thomas (defensive end), Stanford: The Jaguars will examine Texas A&M’s Myles Garrett and Alabama’s Jonathan Allen, but it would be a big surprise if either were available when the Jaguars pick fourth, so Thomas is a more realistic possibility. Thomas (6-2, 275 pounds) played all over the defensive line in two seasons with the Cardinal, and while he only totaled 11.5 sacks, he did make a lot of plays behind the line of scrimmage: 24.5 of his 98 tackles were for a loss. Some teams may view him as an inside player because he’s a bit shorter than the majority of defensive ends.

Derek Barnett (defensive end), Tennessee: He played both end spots for the Vols and produced double-digit sacks each season: 10 in each of his first two seasons and 13 in 2016. He’s listed at 6-3, 265 pounds, and some teams may project him as an outside linebacker in a 3-4 scheme because he has shown the ability to drop in coverage. ESPN’s scouting report lauds his physical play, ability to shed blocks, discipline and hand usage.

Jamal Adams (safety), LSU: ESPN’s Todd McShay and Mel Kiper Jr. have had the Jaguars taking Adams at No. 4 in each of their two mock drafts, and it’s easy to see why. Adams (6-1, 211 pounds) has the speed, athleticism and instincts to play both strong and free safety, which certainly would allow the Jaguars to mix up coverages and give Gipson the opportunity to freelance a bit. Adams also is a physical defender, and ESPN’s scouting report calls him a difference-maker in run support. The Jaguars may not be bringing back Johnathan Cyprien, and Adams would be an upgrade because Cyprien struggled in coverage.
