The NFL's free agent signing period begins on March 11. What does it really mean? How does it work? Seattle's Doug Baldwin explains it from his perspective in this video.

Some NFL players sign big contracts for big dollars. Some make just the league-mandated minimum, especially un-drafted free agents.

The Seahawks' wide receiver from Stanford, Doug Baldwin, falls into the latter category. Baldwin was not draftec by any NFL team but was signed by the Seahawks three years ago. In this video, Baldwin gives an interesting commentary on NFL free agency.
