Why the 49ers Probably Won't Fire Defensive Coordinator Nick Sorensen
Based on recent 49ers history, Nick Sorensen deserves to be fired.
Let me explain.
Last season, the 49ers defensive coordinator was Steve Wilks, who replaced DeMeco Ryans when he became the head coach of the Houston Texans. Wilks inhereited a defense that gave up 16.3 points per game under Ryans in 2022.
Under Wilks, the 49ers defense gave up 17.5 points per game, or 1.2 points per game more than the previous season. And then in the Super Bowl, they gave up just 19 points in regulation to Patrick Mahomes and the Chiefs. But the 49ers lost in overtime, and a few days later they fired Wilks. Tough business.
Cut to the present.
Under Sorensen, the 49ers defense has given up 22.9 points per game this season. Not great. That's an increase of 5.4 points per game from 2023 when Wilks was the defensive coordinator. So if Wilks deserved to get fired, Sorensen definitely deserves to get fired, right?
Not so fast.
Sorensen's defense had lots of injuries this season. And yet, in a do-or-die game this past Thursday night, the 49ers gave up 12 points and no touchdowns. Sorensen rose up. Meanwhile, Kyle Shanahan offense's scored a measly 6 points. Which means Sorensen outcoached Shanahan in the most important game of the season.
And that's why the 49ers can't fire Sorensen. Because as much as the defense has regressed this season, the offense has regressed even more. In 2023, the 49ers offense scored 28.9 points per game. This season, it has scored just 22.4 points per game. That's 6.5 points per game fewer than in 2023. And that's a huge dropoff.
So before the 49ers fire Sorensen, they first would have to fire Shanahan, and I don't think they have the guts to do that just yet.
