This seems like a no risk scenario. Reclamation projects are usually unsuccessful, but Brown had limited playing time in Carolina. I wonder if he had other issues, since unlike Maybin seems to have legit OLB size and put a few qbs down. He's young, and I'm guessing didn't feast on no-name schools in college like Maybin either. Why not give him a tuesday FA tryout?
What was his deal in Carolina?
Edit: saw several articles stating Brown did not have the strength necessary for the position despite his quick first step.
