1. Can the defense improve enough to get the Falcons to the postseason? Atlanta's defense has been ranked 22nd the past two seasons and has not played well enough to support a playoff run. The Falcons bolstered their defense with first-round draft choice Jamaal Anderson and second-round pick Chris Houston. Anderson figures to be an immediate impact player, pressuring quarterbacks off the edge. Houston could shore up the corner position if he can learn the team's system quickly. With new coach Bobby Petrino being an offensive guru, the Falcons should be better on that side of the ball, but can the defense also improve to make a postseason run? Look for defensive coordinator Mike Zimmer to be aggressive with his play-calling, giving the Falcons a fresh start.
