Carolina faces a defensive rebuild after last year’s historic struggles, but Derrick Brown’s return anchors a revamped line that also features multiple free-agent signees and several rookies. If the newcomers adapt quickly, the Panthers could flip from the league’s worst run defense to something closer to mediocre in 2025, with veteran Adam Thielen adding steadying depth to an offense that can relieve pressure on a thinner defense.

Brown’s presence matters, but it won’t single-handedly fix a leaky unit. The success hinges on how quickly Tetairoa McMillan, Lathan Ransom, Princely Umanmielen, and Nic Scourton contribute, plus how Moehrig, Rozeboom and Wharton perform alongside the new linemen. For fantasy, it’s a nuanced mix: Brown remains a stalwart, while the value of Panthers defenders and receivers grows with improved team efficiency.
