Cowboy Soldiers picked Will Smith in Round 14, thinking him to be the Atlanta closer.  My understanding is that Mark Melancon is the closer, at least to begin the season.  I believe Smith is the better pitcher, and certainly has plenty of closing experience, but the team manager apparently plans to keep Smith in a high-leverage role in the middle innings and hope Melancon can continue to be successful as closer.  If Melancon fails, then Smith might be next in line.
