Upon his signing last year, San Francisco 49ers defensive tackle Earl Mitchell was seen as someone who could help a struggling run defense which ranked last in the NFL the previous season. In fact, no team in franchise history had given up more rushing yards than the 2016 squad.
Pro Football Focus continues its 32-team offseason rankings with the
run defense being the latest entry in the series. The analytics site ranks the 49ers' unit at No. 28 while noting that the team needs a true nose tackle to improve.
"The 49ers run defense rank suffers here from the lack of a true nose tackle," writes Pro Football Focus. "Earl Mitchell's 5.0 run-stop percentage was the worst of any player in the NFL last season that had at least 300 snaps against the run."
Below are the top three 49ers when it comes to run-defense grades.
- Reuben Foster, LB, 90.9 run-defense grade
- DeForest Buckner, DT, 82.6
- Arik Armstead, DE, 79.7
The Pro Football Focus analysis team notes that the 49ers missed 11.4 percent of their tackles on run plays, which ranks at No. 16 in the NFL.
The 49ers run defense did see an improvement last year over the previous season. The unit allowed 165.9 rushing yards per game in 2016. That number improved to 116.3 in 2017, which ranked 22nd in the NFL.
Former NFL center turned NFL Network analyst Shaun O'Hara noted on
Good Morning Football on Thursday that the team used three first-round selections on defensive lineman (Arik Armstead, DeForest Buckner, Solomon Thomas) from 2015 through 2017 and used another on linebacker Reuben Foster. That is a substantial investment in the 49ers' defensive front.
"Yet, the 49ers defense ranked dead last against the run over the last two years," O'Hara said.
The 49ers' ranking by Pro Football Focus was the worst among NFC West teams with the Los Angeles Rams coming in at No. 21, the Arizona Cardinals at No. 23, and the Seattle Seahawks at No. 24.

49ers mailbag: Is Christian McCaffrey being overused? Should Spencer Burford be benched? Is Steve Wilkes who the defense needs? When is Nick Bosa going to show up?
The San Francisco 49ers are 2-0 to start off the 2023 season. In 2021, the 49ers won their first two games but then lost their next four. A win Thursday night, in the home opener against the New York Giants, would be the 49ers' first 3-0 start since 2019. That season, the team started out 8-0 before going on to win the NFC West and cruise through the NFC playoffs on their way to a birth in Super Bowl LIV.
I can't seem to remember how that game turned out, though. It's like it's been blocked from my memory.
It doesn't matter, because we've moved on to the current season. And to celebrate the 2-0 start, we've opened up the mailbag to answer those questions burning a hole in your mind. So let's get to it.

49ers mailbag: What are the keys to beating the Cardinals? Can Arizona run on SF? Is Steve Wilks better than his predecessors?
A week ago, it seemed like the Arizona Cardinals would easily fall to the San Francisco 49ers. But after the Cardinals handled the Dallas Cowboys to notch their first victory last Sunday, the 49ers will have to work hard not to overlook Arizona. In the NFL, you really shouldn't overlook any team. That especially goes for teams in your division.
So what are the keys to the 49ers beating the Cardinals and moving to 4-0? Let me give you four quick thoughts:
Don't let Arizona run on you. The Cardinals ran the ball 30 times against the Cowboys and gained 222 yards. They weren't quite as dominant in the two games before that and lost both, but they still had some success, especially against the Giants. According to Steph Sanchez, "Arizona's offense has
