The Green Bay Packers bring a lot of different looks on defense to make their pass rush unpredictable, but they didn't often rush more than five guys last season. They aren't as dependent on the defensive line to create a pass rush as some teams, but when at least two defensive lineman are rushing on every passing down, they do have to provide something of an inside push.
Bob McGinn reported that the defensive line only had 37 (17 games) pressures (total of sacks, knockdowns, and hurries) last season compared to 101.5 (20 games) in 2010. On a per game basis, that's a 250% drop.
Most of that can be accounted for by the departure of Cullen Jenkins, but not the entire difference. At best, Jenkins could have made up for half of it.
B.J. Raji led the D-line with 19.5, followed by Jarius Wynn with 10. Five other lineman accounted for 7.5 in total. And most of the pressure that came from Raji and Wynn happened early in the season (zero sacks for Wynn after September). So the team that we saw down the stretch was even worse than these poor stats indicate.
Sure the defensive lineman would have been helped if the coverage had been a bit tighter, but the secondary also gave up a lot of yards last season on slow developing crossing routes that were given time due to the lack of a rush. That argument works both ways, and doesn't absolve any player from blame.
As I wrote about earlier, this is something they have to address in the draft.
