In the draft I preferred Edmunds over Smith but after watching this video on Smith's background I understand better why we went in this direction. If we consider the on-the-field abilities relatively equal, even if Edmunds and Smith are different types of players, then the leadership qualities and work ethic Smith has will put him in position to become the new leader of our defense.
