NEW ORLEANS – The 49ers’ pass rush can once again be a factor this week.

The 49ers went into their Week 13 game against the Baltimore Ravens knowing they had to make some dramatic changes with their style of getting after the quarterback.

After all, they could not be so aggressive, as 49ers defensive line coach Kris Kocurek teaches, because of the running ability of Ravens quarterback Lamar Jackson.

On Sunday, they can get back to normal against the passing attack of the New Orleans Saints with quarterback Drew Brees.

“Those guys want to get after the quarterback,” 49ers coach Kyle Shanahan said on the 49ers Insider Podcast. “I know the D-line. I know their coach. It was a tough week for them. But they rose to the challenge and played those techniques very well. I thought they did a very good job against Baltimore and stopping the run.

“And now this week, you still got to stop the run. It always starts with that, but you can play a little more of those techniques you’re used to, which I know they have a lot more fun playing and I know we have a lot more fun coaching it, too.”

It certainly will not be easy for the 49ers’ pass rush to get to Brees, who has been sacked just nine times on 249 drop-backs this season. Brees gets the ball out quickly, in order to neutralize the 49ers’ pass rush of Arik Armstead, Nick Bosa, DeForest Buckner and Dee Ford.

A week ago, the 49ers played a different style in an attempt to prevent big plays from Baltimore’s quarterback-driven run game. Buckner registered the team’s only sack, and that came for zero yards.

The 49ers gave up some rushing yards, but made adjustments in the second half to limit Baltimore to just three points in the final 30 minutes.

“When you do that, you definitely have to change-up your fronts and play run-first at all times,” Shanahan said. “You got to almost play in a four-point stance and just control people instead of teeing off on guys and trying to go through them. I know last week was a frustrating week.”

The 49ers own the league's top-ranked passing defense, allowing just 134.2 yards passing per game. The 49ers rank second in the NFL with 45 sacks.
