Since his senior year ended, Missouri defensive end Marcell Frazier has been engaged in the most important job audition of his life. As a senior for the Tigers last fall, Frazier played through multiple injuries and still led the Southeastern Conference in tackles for loss. Now he’s working to become the next product of Missouri’s D-Line to take his pass-rushing skills to the next level. NFL teams have drafted nine Mizzou defensive linemen since 2009, including five first-rounders.

While he prepares for April’s draft, Frazier has agreed to write a series of diary entries for STLtoday.
