GB currently sitting at the #11 overall Defense spot. They are currently #2 in passing Defense, even though they lead the league in allowing a ~72% completion rate. Right behind them in completion % allowed are the Vikings, Rams, Chargers, who all run a variation of the same D as Barry. Interesting.
Maybe the D isn't as bad as we think, maybe it feels worse because the team isn't playing complementary ball. The D gets a stop but the O doesn't turn around and score off of it. The O scores but the D gives up a long drive after. Just not playing off of each other, neither side helping the other out.
