The most intriguing prospects attending the 2019 NFL combine

Adderley hasn't faced top competition while at Delaware, but the defensive back excelled in college and shows the versatility to potentially play safety or corner. A strong combine showing could potentially boost Adderley into the first round of the draft.

A legitimate threat to go first overall in the draft, Allen had 17 sacks last season and has great size at 6-foot-5. He's expected to grade well at the combine, and if so, Allen will certainly get some consideration to go ahead of Nick Bosa on draft boards.

A potential first-round pick before tearing his ACL early last season, Anderson has a chance to revitalize his stock with a big showing at the combine. The former Sooners running back had 1,442 yards from scrimmage and 18 touchdowns in 2017, and he can put away some of the questions about his durability with a good showing.

The consensus No. 1 overall pick in the draft right now, Bosa missed almost all of the 2018 season due to an abdominal injury. He has a clean bill of health heading into the combine and could solidify his status as the top player on draft boards.

The best player on a bad Seminoles team last season, Burns is trying to get a first-round grade from teams after recording 10 sacks. He has the quickness to get off the edge, but listed at only 227 pounds despite a 6-foot-5 frame, there are real questions about his ability to hold up against big NFL offensive linemen.

Butler's size really excites teams, standing at 6-foot-6. He had a breakout junior season with 60 receptions for 1,318 yards and nine scores, showing himself to be a more than capable deep threat, but he has to show solid hands in drills at the combine to slip into the first round.

Fellow Iowa tight end T.J. Hockenson is getting much of the early press, but Fant has also shown the production and athleticism to be a first-rounder. Strength is one of the biggest question marks about Fant heading into the combine, but he could possibly even jump Hockenson if he shows progress.

One of the most athletic offensive linemen at the combine, Ford has the ability to play almost anywhere on the line. Despite slightly lacking tackle height at 6-foot-4, Ford is listed at nearly 340 pounds and is expected to grade out among the elite linemen in testing.

A former elite recruit at Michigan, Gary is expected to grade off the charts in combine testing. His career at Michigan was as good as advertised, and if he holds serve, Gary looks like a potential top-five pick.

Hardman is the type of speedy talent that Al Davis would love. He wasn't all that productive as a wide receiver at Georgia but served as the team's primary kick returner and could challenge  for elite numbers in the 40. If he's able to run a sub-4.3, Hardman could find his name called early in Day 2 of the draft.

Hill could help himself as much as any running back at the combine. The speedster averaged 5.6 yards per carry in a productive three-year career for Oklahoma State and profiles well as a third-down back at the highest level if he can show capable hands on top of the speed.

Hockenson is likely to be the first tight end off the board during the draft and can solidify that status at the combine. He had a breakout sophomore season with 49 receptions for 760 yards and six scores, and his physical traits jump off the page at his position. Iowa's strong history producing NFL talent at the position is another bonus for Hockenson.

Holyfield is built like a prize fighter, which isn't a coincidence given that his father is former heavyweight champ Evander Holyfield. He never got a full workload at Georgia but finished last season with 159 carries for 1,018 yards and is an absolute load to bring down once he gets going. It's possibly Holyfield will be the first running back off the board if he impresses at the combine.

It was somewhat of a surprise that Jackson opted to leave Buffalo for the NFL, but he's one of the most interesting developmental quarterbacks in the draft. He has a strong arm and can run, and a nice showing at the combine could make him a second-day pick.

Lawrence was suspended from the College Football Playoff for testing positive for a banned substance, but it won't take much for him to get back into the first round. Standing at more than 350 pounds, Lawrence is a prototypical run stuffer but has great quickness for his size. If he grades well in the combine, as expected, Lawrence has a great shot to be called on Day 1.

Mack really didn't come on until his senior season despite high expectations, but capping off that breakout showing with a strong combine should allow him to become a Day 2 pick. He has the versatility to play in multiple defensive alignments and profiles well as a nose tackle if he backs up what looks like elite strength.

Coming off an injury-plagued season, Metcalf is gaining steam as the top wide receiver on the board. He has great physical attributes and an NFL pedigree, with his grandfather (Terry Metcalf) and uncle (Eric Metcalf) having productive NFL careers. If he runs a 4.4 40-time, as expected, Metcalf should be able to finish off his first-round grade.

Murray's lack of height is well-documented, but he's one of the best athletes we've seen at quarterback. It's full speed ahead for Murray's football career after giving back his first-round MLB bonus, and with a strong combine he could convince teams that he's a top-five pick.

Montgomery was highly productive for the Cyclones over the last two seasons, finishing with more than 1,300 yards in both years. There are some teams that will shy away from his heavy workload and sub-5.0 yards per carry overage, but Montgomery has Le'Veon Bell upside with a polished game that should do well at the combine.

Oliver was a five-star recruit at Houston and showed every bit of that ability in college. He could be the most athletic defensive tackle at the combine, and if he does enough teams should fall in love enough to take him within the top five picks in the draft.

Sweat was the talk of Senior Bowl practice and can continue the momentum at the combine. He had a combined 22.5 sacks over the last two seasons and is still maturing physically, but a strong showing could loft him into the top half of the first round.

White is currently the top pure linebacker prospect available and could get a nod in the top five of the draft if he holds up at the combine. There weren't many faster linebackers in real-game situations.

More than a few scouts have Williams as the most talented player in the draft after a breakout 2018 season at Alabama. He's younger than most other prospects having just turned 21, and he is almost certainly a top-five pick if his measurables hold up in testing.

The second tier of cornerback prospects is fluid, and Ya-Sin has a chance to get ahead of the class. He's physically gifted and has the traits to make scouts fall in love after watching him in drills against other defensive backs.
