The Detroit Lions are looking to solidify their defensive line heading into the 2025 season after a strong 2024 campaign, despite facing challenges such as injuries and contract expirations. Alim McNeill continues to rise as a star, securing a lucrative four-year deal. However, the availability of key players like Levi Onwuzurike, a free agent, raises concerns about depth. DJ Reader's performance as a nose tackle remains steady, and the Lions' pass-rush metrics need improvement to elevate their defense further.

With Onwuzurike possibly leaving and McNeill's injury status uncertain, the Lions' front office faces pressure to bolster the defensive line via free agency or the draft. Their success hinges on the development of younger players like Mekhi Wingo and Brodric Martin, alongside retaining veterans to ensure a robust rotation.
