Top things to know from Matt LaFleur’s press conference introducing new defensive coordinator Jeff Hafley.

Green Bay Packers coach Matt LaFleur answered questions with the assembled media at Lambeau Field after constructing his new coaching staff — including defensive coordinator Jeff Hafley — for the 2024 season and before the start of the NFL Scouting Combine.

Here are the top things to know from the session:

— “A lot of thought and deliberation” went into making a change at defensive coordinator. Called it a “tough decision” to replace Joe Barry but acknowledged it is his job to make tough decisions to help the team.

— Interviewed a lot of candidates, many went on to get coordinator jobs elsewhere. Impressed with Jeff Hafley’s ability to lead and connect. “Excited to see what he’ll bring.”

— LaFleur confirmed the defensive scheme will change, suggesting a 4-3 base. Expects the pieces in place will make an easy transition.

— On defense’s emphasis: “I want us to be fast and physical, and attack the ball. We will be a little more vision-based on the backend.” Thinks the vision to the quarterback will help create more takeaways.

— On Hafley’s experience as a head coach: “He’s sat in the same seat.” Has that perspective, and the two can bounce ideas off each other.

— Emphasis on “making it easy.” Can’t overload players. Want players playing fast. Knowing personnel is key.

— “Definitely” appealing that Hafley comes from a defensive back background. Will “lead from the backend.” Believes Hafley has a great knowledge base of all three levels.

— More vision based? “More visuals on the quarterback.” Reiterates that a big part of the coverage plan will be having more eyes on the quarterback.

— Replacing Chris Gizzi at strength and conditioning coach was another “tough decision.” Didn’t blame strength department for soft tissue injuries in 2023. Said new leadership could be “beneficial.” Likes newcomer Aaron Hill. LaFleur has close relationship with Dustin Perry, the 49ers strength coach and his wife’s first cousin. Hill worked under Perry for five seasons.

— LaFleur said Sean Mannion will be an offensive assistant, working primarily out of the quarterback room. “Love his past experience, coached him before.” Respected his process, the way he prepared. LaFleur said Mannion was getting ready to interview with Bears, so the two jumped on a Zoom call. Mannion eventually picked Packers over Bears. “He’s going to have a bright future for us and in the coaching profession.”

— Defense is about style. Attack the football, approach the ball carrier, relentless every play, effort. Staple of 49ers, Jets, Texans defenses. “It comes down to style of play.”

— Confident the new defensive coaching staff will bring “energy” that translates to the players and product on the field.
