The Niners have a sack rate of 4.9%, which ranks 26th in the NFL and on pace to be the lowest of the Shanahan era. For context, the 2019 team was at 8%.
- San Francisco has 15 sacks, which is tied for 18th in the NFL. It's on pace for 36, which would be its third fewest since 2017.
- The 49ers' pressure rate of 27.6%, which 22nd in the NFL and on pace to also be the lowest since Shanahan and Lynch arrived.
But it's also fair to point out that Wilks has, on multiple occasions this season, been forced to lean into an aggressive approach because the front four isn't getting home consistently.
When the Niners don't blitz, they have a pressure rate of 23.5%, which is 23rd in the NFL. When they do, it's 40.5%, which ranks 18th. Perhaps Wilks is feeling out the best ways to deploy his blitz packages or how to use certain players, but the fact that the Niners aren't even in the top half of the league in pressure percentage -- let alone sacks -- with and without the blitz indicates that one of their foundational pillars is showing some cracks.
To be sure, opposing offenses are game-planning ways to try to neutralize the Niners' star-studded line. The ball is often coming out quick, which explains the significant gap in the Niners' pass rush win rate (eighth-best) and their pressure rate (22nd), and teams are sending extra blockers at Hargrave, Armstead and Bosa with regularity.
