This article is a year old and it touches on the trend of league defenses blitzing less.

Last year in this foreword, we explored the concept of space and how offenses were getting increasingly better at manipulating it to set up big plays and create yards after the catch. What defenses are doing now is in reaction to that — limiting the space an offense has to work with.
The increase of two-high safety shells was in part to limit the explosive pass plays.
To fight against this, offenses have gotten the ball out quicker and shorter passes have increased. The average depth of target has dropped over the past three seasons from 8.18 in 2019 to 7.79 in 2020 to 7.75 in 2021, per TruMedia. The rate of passes thrown at or behind the line of scrimmage has risen each year since at least 2013 and in 2021, 71.4% of passes were thrown within 10 yards of the line of scrimmage.
With so many passes getting thrown to that area, the defensive adjustment has been to flood more defenders into throwing lanes. That has come at the expense of blitzing aggressively.
(In 2021), defenses blitzed just 25.3% of the time, the lowest rate over a full season since at least 2013, per TruMedia.
In 2021, defenses rushed four on 69.9% of plays. That would have been a top-10 rate for a singular defense in 2020. 18 teams were above 70% in 2021.
More defenses have used simulated pressures, which shows the threat of a blitz with multiple players around the line of scrimmage only to rush four, but disguising which four players is the point. This can give similar effects to a blitz by manipulating protection rules and potentially creating free rushers, but still getting seven defenders back in coverage.
-----------------------------------
I'm not a fan of blitzing just because it's a part of the DC's DNA. Blitz when it is the optimal way to combat the offense they are playing against on that Sunday, in that specific game time situation. The 49ers have two of the best pass rushers in Bosa and Hargrave. A benefit of having those two is not having to blitz so much and being able to put 7 in coverage. I hope Wilks finds that happy medium where he increases the 49ers blitz rate, when compared to Saleh/Ryans, but also doesn't feel the need to blitz just because that's a part of who he has been in the past.
I get what you are saying but it will be hard to diagnosis this form the sidelines. Your past is your present in some regards so it'll be hard to totally change his philosophy now. I would think he's smart enough to realize when to dial back or ramp it up. To me DR seemed to blitz more than Saleh. I hope we see more A gap blitzes. Let our linebackers get in the mix. Definitely will be interesting to see the mix.
