Yes, it's a small sample size, but the Pats are currently rated third in the NFL in pass defense, per Football Outsiders' Defense-adjusted Value Over Average ratings.
While the team hasn't collectively played well by their own phenomenally high standards, New England's secondary has held its own, albeit against two rookie QBs.
They've allowed less than 200 yards passing in each of their first two games, yielding a 53 percent completion rate and an average of 5.5 yards per catch. How good is that? If a quarterback had put up a season-long 53 percent completion rate and 5.5 YPA in 2012, he would have been last in the NFL in both categories.
The Patriots' defense has also been opportunistic, generating four forced fumbles (tied for second-highest in the NFL) and three INTs (tied for third-highest) in their first two games.
Of course, there are plenty of reasons to temper early excitement over the performance of the defense. Both offenses they've faced rank in the bottom half of the league in terms of total yards last season. Both are also integrating rookie quarterbacks.
The Patriots' pass defense will face a sturdier test in Week 3 against Josh Freeman, who even while disgruntled, is a talented player coming off a solid year. He has a prime target in Vincent Jackson, one of the league's top receivers who is averaging 19.3 yards per catch and 116 yards per game in his first two weeks.
The Pats must hope that top cornerback Aqib Talib is healthy after missing practice this week. Talib and second-year corner Alfonzo Dennard are a strong pair of physical cornerbacks capable of playing man-under press coverage.
With Devin McCourty and the surprisingly effective Steve Gregory manning the safety spots to go with Talib and Dennard underneath, the Pats may have their best defensive backfield in a long time.
If the Pats' secondary can be this effective going forward, New England can win games even when their heralded offense isn't up to snuff.
