Quietly, Barry's defense has averaged 15.75 points against per game in the past 4 games. For context, the Bills and Cardinals lead the league at 16.3 points against per game. So that 15.75 would be good for the best in the league if it were extrapolated over the first 7 weeks of this NFL season.
Obviously there were a couple of 30 burgers in the first couple weeks of the season, but largely the Packers defense has been more than solid (minus red zone stops) since the 2nd half of the Detroit game.
I was against the Barry hire, and I'm still not overly crazy about it, but you cannot argue with the numbers. The offense hasn't been clicking on all cylinders, so this defensive production has been crucial to getting to 6-1.
The past 4 games haven't exactly been murderer's row of offensive firepower as a whole, but it did include the Bengals who just dropped 41 on the Ravens.
I have to give credit when due. We will know more as we get tested against the likes of the Cardinals and Chiefs, but to do what we've done without key guys in a lot of these games, it really speaks to how well Barry and his staff have done so far.
