Jon Meoli, reporter: Thursday couldn't have gone better for the Ravens' starters — a sustained touchdown drive for the offense, and two three-and-outs from the defense. But the rest of the game leaves plenty of questions about the team's depth at a lot of positions, especially on defense. The top reserve safeties appear to be a converted cornerback and a safety who played cornerback last year. The defensive line is so thin that Carl Davis and Lawrence Guy played all four quarters. The Ravens will have the weapons and scheme to score some points this year, but after such promise early in camp, the back end of the defense left a lot to be desired.
