Heading into the 2025 NFL season, the Philadelphia Eagles boast the top-ranked linebacker unit, highlighted by standout Zack Baun, who earned a league-high 90.2 PFF grade last season. Newly drafted Jihaad Campbell is expected to bolster their already formidable group alongside Nakobe Dean and young talents like Jeremiah Trotter Jr. and Smael Mondon Jr.

In the second spot, the Detroit Lions are represented by Jack Campbell, who is cementing his status as an emerging star after a strong 2024 season. The New England Patriots' linebacker corps is deepened by new acquisitions like Robert Spillane, while the Kansas City Chiefs rely on Nick Bolton and Leo Chenal to lead their defense.
