The New England Patriots have put a better defense on the field as it has allowed only 264.5 yards per game, but they've faced limited offenses in the Tennessee Titans and Arizona Cardinals.
The Ravens' offense, which sputtered in a 24-23 lost the Philadelphia Eagles last week after thrashing the Cincinnati Bengals in the opener, is at a crossroads, too.
Which performance in the first two weeks represents these teams' actual identities on offense and defense?
Baltimore's rejuvenated receiving corp failed to get separation against the physical secondary of the Eagles as Joe Flacco only completed 22 of 42 passes against their Cover 1 scheme, using just one safety over the top to play the deep zone.
In the Patriots, the receivers will face a lot of Cover 2, which means safeties Patrick Chung and Steve Gregory playing the deep zones.
"In Cover 2, they have to slow you down and it kind of makes it tougher," said Torrey Smith, Baltimore's fastest player who only has four catches for the season. "They do a good job at putting their hands (on) you so we just have to work our technique."
With linebackers Jerod Mayo and rookie Dont'a Hightower, the Patriots still can stuff the run in Cover 2. They held Titans running back Chris Johnson to four yards on 11 carries and Cardinals runner Beanie Wells to 44 yards on 14 carries.
Ray Rice has 167 yards on 26 carries, which is better than six yards per carry this session.
In last year's AFC title game, Rice gained just 67 yards on 21 carries. In a 2010 regular season matchup, it took 28 carries for Rice to get 88 yards.
Smith being able to stretch the field would go a long way in loosening up the Patriots' defense.
"I'm not panicking at all," Smith said. "I haven't had the ball thrown too many times my way. It's not that I'm not open or Joe is not looking for me it's just the progression at times. We'll get there."
