JACKSONVILLE, Fla. -- Conventional wisdom says the Jacksonville Jaguars are going to take a pass-rusher with the third overall pick in the upcoming draft.

It’s a foundational piece of building a franchise. Teams need elite or very good players at quarterback, left tackle and as pass-rushers to have a chance to win at a high level in the NFL. The Jaguars believe they have two of those pieces in Blake Bortles and Luke Joeckel, and it would be logical to add the third later this month.

The question: Which one?

Leonard Williams, Dante Fowler Jr. and Randy Gregory are three players that have been linked to the Jaguars in various mock drafts. Each is a different type of player and the Jaguars will have to decide which style they like best. ESPN Stats & Information broke them down and provided some interesting nuggets about each.

Leonard Williams (USC)

He is the biggest of the three at 6-foot-5 and 302 pounds and he’s also the most versatile. He can line up at end or tackle and his pass-rush production didn’t drop off when he moved inside. Half of his seven sacks in 2014 came at end and half at tackle.

He was a load to handle, too. He beat double-teams to record three sacks, which was second only to Missouri’s Markus Golden among the top 15 defensive line prospects.

Williams is regarded as the best defensive player in the draft – and arguably the best overall player – and Tennessee would have to pass on him at No. 2 for the Jaguars to get him. The Titans also are reportedly considering Oregon quarterback and Heisman Trophy winner Marcus Mariota, and if that scenario plays out, the Jaguars would take a player that can line up anywhere along the defensive line and create problems for offenses similar to the way J.J. Watt does in Houston.

Dante Fowler Jr. (Florida)

The 6-3, 261-pound Fowler also lined up at several spots while compiling 8.5 sacks and an SEC-high 37 pressures (hurries plus knockdowns) in 2014, but he’s going to be a defensive end in the NFL because he’s too light to hold up at tackle.

Fowler seems to have the whole package of pass-rush moves. He recorded four of his sacks using power moves (bull rush or swim moves) and 4.5 using finesse moves (spin moves, speed rushes). He was one of only five players ranked in the top 15 draft prospects at end, tackle, and linebacker to have at least four sacks using power moves and four using finesse moves.

Randy Gregory (Nebraska)

The 6-5 Gregory is the lightest of the three (235 pounds) and he doesn’t project as a traditional defensive end, but he would fit as a pass-rushing "Leo" outside linebacker for the Jaguars. However, he did have very good production when he rushed from either a three-point or four-point stance: 13.5 of his 17.5 sacks in the last two seasons came when he lined up with his hand on the ground.

If the Jaguars are going to take a pass-rusher at No. 3 it will come down to which style they prefer. Williams doesn’t fit the "Leo" spot, but Fowler and Gregory do. Williams could give the Jaguars a pass rush from multiple spots. Paired with tackle Sen'Derrick Marks, he would give the defense very good pressure up the middle.
