Retirement? I don't think this word means what you think it means. After a year off, 66-year-old Bruce Arians is back in the league. This pairs a head coach who loves to go deep with a quarterback who's best throwing deep, so it seems like a good marriage. Arians apparently will come as a package with his former Arizona defensive coordinator Todd Bowles, and say what you want about Bowles as a head coach, but he ran some pretty good defenses for Arians with the Cardinals.
