As the Arizona Cardinals prepare for the upcoming 2025 training camp, the projected starting defense is taking shape. Calais Campbell, the veteran defensive lineman, continues to be a cornerstone after leading all active players with 242 career starts. He'll be joined by Dalvin Tomlinson and potentially Darius Robinson or rookie Walter Nolen III on the line. The outside linebacker spots are expected to feature Josh Sweat and Zaven Collins, with Collins' run-stopping abilities making him a staple in the base defense.

In the middle, Mack Wilson and Akeem Davis-Gaither are likely to battle for the inside linebacker roles, with flexibility in their positioning being a key factor. The cornerback depth could see competition, particularly for the slot, where Garrett Williams might take the lead. Overall, the defense is shaping up to be a mix of seasoned veterans and promising young talent, making for an exciting training camp.
