In 2023, the Browns' defense had been ranked first in yards per play allowed at 4.6 and had the lowest total QBR allowed, but this success did not carry over into 2024, where they allowed a passer rating of 59.2.

Cornerback Martin Emerson Jr. had a standout 2023 season but struggled in 2024, allowing a passer rating of 100.5 when targeted, making his performance critical as he enters the final year of his rookie contract.

The Cleveland Browns are determined to restore their elite defense in the upcoming 2025 season after a disappointing performance in 2024, where they fell to 23rd in yards per play allowed.

This decline was evident as the defense allowed 126 explosive plays in 2024, ranking third most in the NFL, which highlighted a significant drop in performance from their previous season.

Defensive coordinator Jim Schwartz emphasized the need for improvement, particularly in third-down defense and takeaways, where the team was tied for the second fewest takeaways in the league with just 12.

Myles Garrett, the 2023 Defensive Player of the Year, remains a pivotal figure for the Browns' defense as they aim to regain their elite status.

To bolster their defensive line, the Browns signed Maliek Collins, who had a high pass rush win rate of 12.7% last season, and he is expected to make a significant impact.

Additionally, defensive lineman Mason Graham, selected in the 2025 NFL Draft, is seen as a strong fit for the defense and has the opportunity to make an early impact following the release of Dalvin Tomlinson.

Rookie linebacker Carson Schwesinger showcased his skills during minicamp and is positioned to fill a significant role due to the injury of Jeremiah Owusu-Koramoah.

Safety Ronnie Hickman, entering his third year, is expected to step into a full-time starting role after the release of Juan Thornhill, and has received praise for his ball-hawking abilities.
