4. Terrell Lewis, Alabama – Biggest mystery

Height/weight: 6-5, 262

2019 stats: 31 tackles, 11.5 tackles for loss, 6.0 sacks, one fumble recovery

Combine results: 40: DNP, Bench: DNP, Vertical: 37.0, Broad: 124.0, 3 Cone: DNP

Scouting report: The evaluation requires both projection and a small leap of faith due to durability concerns after he missed most of two full seasons. He needs to fill out his long, athletic build with more girth and muscle to help set stronger edges and hold his ground against downhill rushing attacks ... – Lance Zierlein, NFL.com

Draft projection: Day 2

What Lewis says about his game: "Obviously, I feel like I'm versatile as far as the player on the field. You've seen me play at the edge, rush from three-technique, play at the nose, play stack backer and drop back into space and stuff like that. I try to express to teams that, you know, I can play in multiple ways."

Twentyman: He's going to test well at Alabama's pro day March 24, and then teams will go back to work on the tape. He's probably the toughest edge rusher in this class to evaluate because of all the injuries and missed time. When healthy, however, he was productive, but how much will those injuries be part of his story moving forward?

5. Marlon Davidson, Auburn – Bull rusher

Height/weight: 6-3, 303

2019 stats: 48 tackles, 11.5 tackles for loss, 6.5 sacks, one forced fumble, one fumble recovery

Combine results: 40: 5:04, Bench: 21, Vertical: DNP, Broad: DNP, 3 Cone: DNP

Scouting report: Davidson has average height and a thick/square build. He typically lined up at defensive end for the Tigers, but also possesses the ability to slide inside. As a pass rusher, he is devastating when he has a runway. He generates a lot of power in his bull rush and has an array of hand moves he can incorporate on the move. He doesn't have an elite get-off, but he wins in the ways just mentioned ... – Daniel Jeremiah, NFL Network

Draft projection: Day 2

What Davidson says about his game: "I still see my role as a strong-side defensive end, moving to 3-technique inside, pass rush type of thing. I'm just getting a lot stronger so my body mass is growing a lot. I'm really taking up with a lifting weights type of thing, but it's nothing too much that you can't get off, 8 to 10 pounds, that's not too bad."
