The new-look Ravens D certainly looked like a heavyweight contender in the preseason, surrendering a grand total of 32 points while ranking No. 1 in total defense, rush defense and pass defense. Yeah, just the preseason. I know. But while the preseason generally isn't an accurate gauge on how a team will perform during the regular season, you can certainly get a feel for a roster's talent, chemistry and continuity when the 1s are on the field. After watching Baltimore's starters in preseason action, it's apparent that the defensive backfield upgrades will allow the Ravens to play tighter coverage, giving the pass rush more time to get to the quarterback. Baltimore's spectacular preseason work resulted in the Ravens holding opposing quarterbacks to a 46.6 percent completion rate and a 51.8 passer rating. Those numbers not only led the NFL, but they were well below the typical efficiency marks for passers in the preseason.
