The Kansas City Chiefs made another addition to their defense on Saturday with the selection of former Stephen F. Austin edge rusher BJ Thompson.

Here are five things to know about the Chiefs' newest pass-rusher.

1. Thompson is a long and athletic edge rusher with good speed.

The 24-year-old Thompson checks in at 6-foot-6 and 243 pounds with nearly 35-inch arms to go along with impressive speed.

Here's more on Thompson's physical profile from The Athletic's Dane Brugler:

"…His speed and length make him a tough guy to keep blocked when he stays under controlled mid-rush. He is a developmental subpackage rusher (reminiscent of Arden Key)."

Thompson agreed with that assessment when asked to describe what he brings to the field as a pass-rusher on Saturday:

"Speed. I was blessed with great athletic ability, so I'm always going to try and use my speed to bend around the edge."

Additionally, Thompson showed off his length and athleticism during a halftime dunk contest a few years ago.

2. He began his career at Baylor before transferring to Stephen F. Austin.

Thompson spent the first two seasons of his career at Baylor, recording four sacks and six tackles-for-loss in 19 games before erupting on the scene at Stephen F. Austin in 2020. He recorded a team-leading 8.5 tackles-for-loss and six sacks in 10 starts that season, earning Southland Conference Newcomer of the Year honors. He then racked up 12.5 tackles-for-loss and 9.5 sacks in 2021 (12 starts) before tallying 6.5 tackles-for-loss and five sacks in 2022 (9 starts).

In total, Thompson recorded 33.5 tackles-for-loss, 24.5 sacks, five forced fumbles and five passes defensed in 52 career games (34 starts) between Baylor and Stephen F. Austin.

3. He also made his presence felt on special teams during his career.

Thompson's combination of speed and length was quite useful on special teams throughout his time in college. Specifically, he tallied a blocked field goal, a blocked extra point and a blocked punt during the 2018 season while playing for Baylor.

4. Thompson showed off his impressive athleticism during his pro day.

Thompson wasn't invited to the NFL Scouting Combine, but he still had an opportunity to demonstrate his athletic skills during Stephen F. Austin's pro day. Here's a quick look at some of his results and how they compared with those in his position group who were at the Combine.

Vertical Jump: 37.5 inches (would have tied for third among defensive ends at the Combine)

Three-Cone Drill: 7.06 seconds (would have ranked third among defensive ends at the Combine)

Broad Jump: 10 feet, five inches (would have ranked seventh among defensive ends at the Combine)

It's also worth mentioning that Thompson landed on The Athletic’s “College Football Freaks List” back in August due to his incredible physical traits.

5. Thompson is a native of England, Arkansas and is the younger brother of a former Chief.

A town of less than 3,000 people about 30 minutes from Little Rock, England clearly holds a special place in Thompson's heart. He spoke about his relationship with his hometown at length on Saturday.

Coincidently, Thompson isn't the first member of his family to spend time with the Chiefs. His older brother, Blake Mack, signed with Kansas City as an undrafted free agent in 2018 and participated in training camp that summer. Mack didn't end up making the Chiefs' regular-season roster, but he was still able to provide some insight into Kansas City's program.

"He told me to be patient and to grind every day. Nothing is going to be handed to you, you have to prove yourself every day," Thompson said. "You have to go out there and take it, because there's always somebody else who wants it just as badly as you."

Thompson will have that opportunity over the next several months as a member of the defending Super Bowl champions.
