Atlanta''s health situation: The Falcons played last week without QB Matt Ryan and RB Michael Turner. They were unable to generate much offense without their two stars, and both may miss this week''s game as well. Regardless of whether or not they play, Atlanta must find a way to improve offensively, or it has no chance of beating New Orleans.Mike Smith''s defensive game plan: When Atlanta hired Smith, he was known as a sound defensive coordinator, who excelled at getting the most out of his players. The Falcons'' struggles this year, however, have come on defense, and it gets no easier for Smith and his staff with the Saints'' top-ranked offense coming to town.Robert Meachem''s emergence: New Orleans'' patience with its 2007 first-round pick is paying off this season. After making little impact during his first two seasons, Meachem has become one of Drew Brees'' go-to targets. He has seven touchdowns in the last five weeks (including a defensive score), and has scored at least once in all five games.
