Dee-fense: Why Dee Ford is so Valuable to the 49ers

Jan 9, 2020 at 10:00 AM4



Coming off a disappointing 2018 season for the 49ers defense, the primary area that needed improvement was the pass rush. The 49ers weren't able to generate consistent pressure with their front four, leaving their young and inexperienced defensive backs exposed on the back end, where they were routinely picked apart by veteran quarterbacks.

Clearly, the 49ers brass recognized and attempted to address the lack of a pass rush over the past offseason, as they drafted Nick Bosa second overall and invested significant capital (both draft and financial) by trading a second-round pick for Dee Ford and extending him with a lucrative contract.

The team's investment paid dividends early in the season, as a dominant 49ers defense led the team to an 8-0 start as the offense struggled at times to find its rhythm through some shaky performances by Jimmy Garoppolo. Through its Week 12 game against Green Bay, the 49ers defense accumulated 44 sacks on 324 dropbacks, for an impressive sack rate of 13.5%. In its final five games, however, that number has plummeted. The defense has collected only five sacks combined on 188 dropbacks, for a middling sack rate of just 2.7%.

Why the dramatic decline?

Luckily for the 49ers, the answer can be found in a player (hopefully) slated to make his return this week against Minnesota. Ford injured his hamstring in Week 11 against the Cardinals and has played only four snaps since, almost exactly coinciding with the drop off in productivity of the 49ers pass rush.

Ford himself only has 6.5 sacks on the season, so at first glance, losing him shouldn't have this profound of an impact. His presence, however, allows all the other pieces on the defensive front to slot into roles they can excel at.

The 49ers don't really have an effective backup edge rusher on their roster, as they've failed to find one either in the draft or by taking flyers on veteran free agents. With Ford sidelined, the 49ers have compensated by moving defensive tackle Arik Armstead to left end on passing downs. Armstead is a much more natural defensive tackle, where he's able to use his enormous reach advantage (Armstead is listed at 6'7″) and heavy hands to manhandle shorter interior linemen, especially when rushing the passer.

When playing on the outside, however, Armstead's reach advantage is mitigated by facing opposing tackles, who are generally taller with longer arms than interior linemen. Armstead's stats show starkly how much more effective he is on the inside. Through the Week 12 game against Green Bay, a resurgent Armstead had 10 sacks on the season. He hasn't recorded one since.

Moving Armstead outside also necessarily means the 49ers backup defensive tackles see more snaps, and injuries and ineffectiveness have racked that group. With the criminally underrated D.J Jones out for the season, Jullian Taylor (since injured as well) and Soloman Thomas have received more playing time. Both are serviceable players against the run, but neither has the dynamic pass rush ability that Armstead and fellow stud tackle DeForest Buckner have. Thomas played over 60% of the team's defensive snaps in Weeks 15 and 16 despite cracking 50% just once before that, and still only has two sacks on the year.

Losing Ford is like losing two players — an outside speed rusher (Ford) and a dominant interior player in Armstead, who is forced to move to a role in which he's far less effective. It wouldn't be a surprise at all to see the 49ers try to add another edge rusher this offseason even though they already have two great young players at the position in Ford and Bosa.

If anyone needs justification for why Ford got the enormous contract extension he did, look no further than the impact his absence had. With Ford on the field, the 49ers have one of the most fearsome pass rushes in the entire NFL. Without him, they barely have one at all.

    I get what he is saying and I agree. The issue is not that we are not creating pressure on the QB as not getting sacks. Getting a sack is great but if you force QBs to throw earlier etc is just as good as well. Also teams are scheming differently by throwing the ball quicker usen med to short throws. Then the 2nd half look at who we faced v the first half of the season.

    RED END ZONE been missing that. Debo, Emmanuel, George, Raheem, Juszczyk, Tevin, Kendrick, Richie dancing in the red. & don't forget, there are more ways to score on defense than on offense .......

    How easy is it to get three good or better pass rushers in an off season? I don't care about Dee Ford missing games as long as they can win three more this season.

    "The 49ers don't really have an effective backup edge rusher on their roster, as they've failed to find one either in the draft or by taking flyers on veteran free agents." JESUS H. CHRIST! The SF 49ers trade a second round pick to get Dee Ford and expend the 2nd overall pick in the draft to get Nick Bosa, and we get a statement like THIS? The 49ers FAILED to get a THIRD pass rusher to sit on the bench until Ford or Bosa or both get injured? WHERE DO YOU FIND CLOWNS TO MAKE IDIOTIC STATEMENTS LIKE THIS? Do you have an editor who can throw pablum CRAP like this back in the author's face and say TRY AGAIN? Or do you just let people burp up whatever they had for lunch and print it as the gospel?

49ers GM John Lynch gives a thumbs-up to Nick Bosa's recovery but isn't certain about Dee Ford

By Kirk Larrabee
Jan 4, 2021

There's good news and not-so-good news for the San Francisco 49ers on the defensive end front as the 2020 season comes to a close. No position on the San Francisco 49ers was hit harder with injuries over the course of the 2020 season than defensive end, with the absences of Nick Bosa and Dee Ford in particular resulting in a significant negative impact for the team's pass rush. But while all signs are positive in terms of Bosa being ready for the 2021 season, it sounds like things aren't as certain when it comes to Ford. 49ers general manager John Lynch discussed the current status of each player during his year-end press conference on Monday, and while his tone was upbeat about Bosa's recovery from a season-ending torn ACL, he sounded much less optimistic in

There's a growing buzz in league circles that Deshaun Watson could ask to be traded, and his new contract doesn't make that as difficult as you'd think

By Tim Sprinkles
Jan 4, 2021

The 2020 season has tormented 49ers fans with an unprecedented and shocking number of roster moves and free-agent signings due to injuries, COVID, and poor performance. When the season began, there were dreams of pursuing a sixth Lombardi Trophy, and now, after a Week 17 loss to the Seattle Seahawks that dropped their record to 6-10, the 49ers and their fanbase have shifted their focus to the offseason and the 2021 NFL Draft. With 38 scheduled free agents on the roster, there is one player who John Lynch shouldn't question re-signing: Taybor Pepper. Early on in the season, the 49ers had a crisis at the long-snapper position. Kyle Nelson, the longest-tenured member on the roster after Joe Staley retired, was having trouble with his snap accuracy, at some points even bouncing
