49ers Defense Grades

Defensive Line

The entire Niners defense dominated, and it started up front. Nick Bosa had 1.5 sacks, Drake Jackson had the other half, and the defensive line ended up controlling the entire game. There was little Seattle could do on offense, and it stemmed from the defensive line being in absolute control of the run or pass game.

It’s the type of display San Francisco needs in the future.

Grade: A+

Linebackers

Nothing splashy from the game for the linebackers (Fred Warner’s interception was taken away by a PI call), but there were no major missed tackles and no coverage busts. The linebackers reacted quickly and tackled decisively.

Grade: A

Secondary

In the past, the 49ers were burned by Seattle’s receivers. Now-Denver Broncos quarterback Russell Wilson was no longer back there, but even if he was, there wasn’t much to throw to.

San Francisco’s secondary put on a clinic. It crashed hard against the ball, was stellar when asked to cover, and took on the challenge of Seattle’s receivers extremely well. One blemish could be Hawks wideout Tyler Lockett’s 100-yard game, but the nature of it was so quiet and so non-threatening, it becomes a small statistical anecdote.

Grade: A+
