In a new offseason series, Insider takes an in-depth look at NFL teams before free agency begins on March 12. What is each team's philosophy on offense and defense, biggest needs and one player who could make for an ideal signing in free agency?

Team philosophies

Offense -- As much publicity as this pass offense generates, running the football is still very important for the Ravens. They can show a physical two-back look with fullback Vonta Leach and running back Ray Rice, or they can go to one-back sets and spread things out. They have gone from a power man-blocking offensive line to more zone schemes and even an occasional stretch play. Rice is an excellent one cut-and-go back.
