The San Francisco defense is 24th overall in the league, allowing an average of 352.9 yards per game, and 27th in passing defense, giving up 249.1 yards per game through the air. Some of that is skewed after allowing 452 passing yards to Jacoby Brissett last week.

Despite injuries that have ravaged the 49ers’ defense (Nick Bosa, Fred Warner, Yetur Gross-Matos, Mykel Williams, to name a few), and put them at the bottom of the league in total sacks (12), Young sees a group on tape under coordinator Robert Saleh that can still wreck a game plan.

“A really good group, a group that plays together really well, you could tell how much they’ve embraced the scheme, how well they play it, they communicate really well, they’re dynamic at all three levels,” Young said. “Up front, it’s a really cohesive group. They work really well in the run-pass game to disrupt things.

“The second level, play really well together, very physical, fast, and then, a really good, really good third level as well, in the secondary. Do a great job of matching patterns and being sticky in man coverage, do a good job of getting after the ball and disruption, and then in zones being where they’re supposed to be in their spots.”
