If there was one big takeaway from watching a month's worth of Detroit Lions training camp practices, it was how much more competitive their defense was. In fact, the defense beat the offense in a scrimmage-style practice that concluded training camp.
If the Lions are going to accomplish the lofty goals they've set for themselves to begin the season, they know they have to get more consistent production from a defense that finished last season 19th in total defense, 23rd in scoring and 27th against the pass.
In response to those numbers, the Lions completely revamped their secondary this offseason, adding veteran corners Carlton Davis III and Amik Robertson and then drafting cornerbacks Terrion Arnold (first round) and Ennis Rakestraw Jr. (second). They also moved second-year defensive back Brian Branch from nickel cornerback to safety in a move to keep him on the field more and allow him to be an even bigger playmaker than he proved himself to be as a rookie.
Upfront along the defensive line they've added veterans DJ Reader and Marcus Davenport to pair with Pro Bowler Aidan Hutchinson and crafty veteran Alim McNeill. Fourth-year defensive lineman Levi Onwuzurike was really good throughout camp and was mentioned a couple times by head coach Dan Campbell unprompted on Monday as a player who could make a huge impact upfront. They are certainly much deeper upfront than they've been heading into previous regular seasons.
Left tackle Taylor Decker was asked about Detroit's defense on Monday, and he said the play of the defense in camp and the improvements they've made upfront really stood out to him.
"That defensive line is much improved, in my opinion," Decker said. "They are playing aggressive trying to make plays. Very disruptive front. I think they are playing with a lot of confidence. Definitely a much-improved group from my perspective."
Decker talked about Onwuzurike and the big strides he made this offseason. He also said Hutchinson was poised to take the next step after a Pro Bowl 2023, and mentioned Davenport as having the best bull rush of any edge player he's ever played against.
"I'm excited to watch them play," Decker said of the defensive front.
The Lions just feel like overall they have a much better marriage between the rush and cover aspects of defensive football and hope that leads to more sacks (41 last season; ranked 23rd) and takeaways (18; ranked 18th) too.
"We all know assets were contributed as far as getting some DB's and some D-linemen," linebacker Alex Anzalone said Monday of the improvements on the defensive side of the ball. "I feel like the best way I describe it is we are so much more squared away. Just top down from defensive coaching staff to the bottom of the defense. It's a good feeling going into the season."

Detroit's new-look defense will certainly be tested this week by quarterback Matthew Stafford and the Los Angeles Rams' explosive offense. The Rams ranked seventh in total offense, eighth in scoring, 10th in passing and 11th running the football last season and return all of their core players on that side of the football.
"We're going to be tested," Campbell said of the Rams. "They're going to try to test us and so absolutely, we're going to need to be beefed up ready to go up front."
It's been a good offseason for the defense and they had a consistently good training camp, but now the real test begins starting this week.
