You are dead on accurate about the corners playing too far off the line, but the rest of your assessment of the defense is pretty far off. The d-line has looked pretty good, despite being inconsistent at times. The MLBs have been very inconsistent, especially in coverage. The OLBs have been awful since Suggs went down. No pressure on the opposing QBs and they haven't been setting the edge well. The only group that has been somewhat consistent is the safeties. As for the offense, the O-Line looks like they still aren't completely healthy from their various off-season injuries and surgeries and so they haven't put together a complete game yet. Overall, the offense has looked like the stronger side of the team, despite the lack of weapons, and Flacco has looked pretty good overall.
