Defensive lineman Jeremiah Ledbetter, Arkansas.

Pick: 6th round, 21st, 205 overall.

Ht./Wt.: 6-3, 280.

Combine workout: Times of 4.84 and 4.85 seconds in the 40-yard dash; 29 reps of 225 pounds in the bench press; 32.5-inch vertical jump; 9-5 in the standing broad.

Pro Day workout: Ran the 40 twice again and lowered his time to 4.81 seconds; increased his vertical jump to 33.5 and his standing broad to an even 10 feet.

Scout Gil Brandt's take on Pro Day: "Looked very athletic in drills. I like this player."

Bio: From Gainesville (Ga.) High School, Ledbetter was a transfer to Arkansas from Hutchinson (Kan.) Community College.

He gave the Razorbacks instant impact after transferring, starting 25 of 26 games in 2015-16. He was credited with 104 tackles, with 15 of them for losses, and 7.5 sacks for the two seasons.

The coaching staff took advantage of his athleticism and versatility. Ledbetter played defensive end all 13 games in 2015 and moved inside to tackle for the first eight games of 2016. He returned to end for the last four games of 2016.

Ledbetter had a strong senior season, leading in tackles for loss (7.5) and sacks (5.5) and was third among linemen in tackles with 49.

**Lions defensive line depth chart:

**

Returning starters – DE Ziggy Ansah, DTs Haloti Ngata and A'Shawn Robinson.

Returning backups – DE Kerry Hyder, DE Anthony Zettel, DE Armonty Bryant, DE Brandon Copeland, DT Khyri Thornton. Additions: DE Cornelius Washington, DT Jordan Hill, DT Akeem Spence.

Tim Twentyman's take: Ledbetter looks to be a pretty big tweener as a 6-3, 280 pound defensive tackle. I wonder if the Lions will try him out at left end as well? He's very athletic and was productive at Arkansas, which means Teryl Austin might have options with him.

Mike O'Hara's take: Looking at his size entering the NFL and the workout numbers he posted, it's hard not to think of what Lions' 2011 first-round pick Nick Fairley looked like when he slimmed down. Ledbetter is another player for the Lions from the SEC. I like how he participated in his Pro Day and improved his results from the Combine – even though those already were pretty good for his position.

QB Brad Kaaya, Miami (Fla.).

Pick: 6th round, 32nd, 225 overall.

Ht./Wt.: 6-4, 214.

Workouts: He did not run or do drills at the Combine or his school's Pro Day. It was reported by NFL.com that Kaaya said he did not participate because of a foot issue, and would run in personal workouts if teams wanted him to.

Bio: After an outstanding high school career in California, he was a three-year starter for the Hurricanes. He departed after his third season as the school's all-time leader in career passing yards (9,968), completions (720) and attempts (1,118). He ranks third all time in school history with 69 career TD passes.

Kaaya had a big 2016 season, completing 261 of 421 passes for a career-high 62-percent completion rate and an impressive split of 27 TD passes to just seven interceptions.

Kaaya started all 38 games the last three seasons and threw 69 TD passes against 24 interceptions.

Media take: Ranked No. 9 among in this year's QB draft class by Bob McGinn of the Milwaukee Journal Sentinel.

Lions QB depth chart: Matthew Stafford returns for his ninth straight season as the Lions' starter. Jake Rudock, a sixth-round pick last year from Iowa and Michigan, began the 2016 season on the practice squad. He was elevated to the active roster late in the year but did not participate in a game. Dan Orlovsky was not re-signed for 2017, giving Rudock the inside track to be Stafford's backup.

Mike O'Hara's take: The Lions were going to have a third quarterback for the offseason. The only question was whether they would sign a young veteran free agent, or bring in a rookie – either a draft pick or a free agent after the draft. Kaaya should get the same opportunity as Rudock to win a roster spot. But the battle is for No. 2, nothing else.

Tim Twentyman's take: Kaaya probably could have used a senior season at Miami. He was a three-year starter in a pro-style offense, and he has some nice physical traits, but like most late-round quarterback prospects, he needs some seasoning. He comes into a good situation in Detroit, where he can sit back and learn from an experienced quarterback room with Stafford and Rudock in the fold.
