Billings is here to make the middle harder to move. At 340 pounds with a decade of experience, he gives Arizona a traditional interior anchor and a veteran voice. He will not be asked to lead the pass rush, but his ability to absorb blocks should make life easier for the younger front players.
Strengths: Powerful nose-tackle build, exceptional starting experience and reliable recent availability. He brings sound run-defense value and can occupy blockers inside.
Weaknesses: He is a 31-year-old one-year signing whose pass-rush ceiling is limited. Arizona has to manage his snap load and cannot expect him to solve a pressure problem alone.
