Don’t Mistake Lack of Talent for Genius: Are Defensive Struggles Due to Scheme or Execution?

It's safe to say that almost no football fan or expert predicted a complete regression of the 2018 San Francisco 49ers. After closing out the 2017 season on a high wave, the expectation for the first .500 season since 2014 felt inevitable.

Unfortunately, due to multiple injuries and a roster that lacks depth, the team is plagued with fundamental errors on both sides of the ball.

Today, Pro Football Focus ranks the 49ers' defense dead last with a 53.5-grade. Last season, the team finished with an overall 70.9 defensive grade, though it ranked 29th overall.

The blowout loss to the Los Angeles Rams added more fuel to an already raging inferno, and lead to more questions about if and when defensive coordinator Robert Saleh would be handed his walking papers.

Is it an unproductive defensive scheme or a lack of talent that's lead to the backslide? Below are a few screen grabs from Weeks 6 and 7. Let's try and decipher the mystery together.

Week 6 – 2nd Quarter, 1st and 10 at the GB 33, 15:00



Green Bay Packers' quarterback Aaron Rodgers threw for 425 yards against the 49ers' secondary. There are plenty of factors why, but milliseconds captured in the shot above showcase a major reason. Circled is defensive back Jimmie Ward 'covering' Green Bay Packers wide receiver Davante Adams during the Week 6 contest.

Ward overran Adams' 15-yard out route and ended up four yards past Adams after he made his break. Five-year veterans should successfully defend an out route, or at least challenge the receiver to make a difficult catch.

There's good news though. The 49ers are executing cover three just as it's drawn up. Everyone is covered except Adams.
In this instance, the scheme is sound, but Ward's blatant error is one of many significant lapses committed by the 49ers this season.

Week 7– 1st Quarter, 3rd and 12 at the SF 46, 8:51



Here's the third play of the Rams' second possession. Salah's called a defense that dropped seven into coverage and rushed four defensive linemen.

I'm unclear how seven defenders leave this much open turf, and allow Rams' wide receiver Robert Woods – highlighted in pink – to make a 28-yard play. Further, look at the receiver in the yellow box. He ran an out-and-up that would have gone for six if quarterback Jared Goff spotted him earlier in his progression.

Week 7– 2nd Quarter, 1st and 10 at the LA 47, 12:52



On the Rams' fifth possession, head coach Sean McVay used a Yankee concept which gained 32-yards. Goff found Woods wide open on the left side of the secondary because the 49ers' defensive back did not drop into the deep third of the field.

Rest assured, three 49ers were covering the underneath crossing route. The 49ers' defense has a bad habit of using three men to cover an opponent. It's happened throughout the season.

I'm more confused why the 49ers continue to get beat deep with the Yankee concept, which they've seen a few times already this season. Has Saleh failed to have the scout team run Yankee? Is it not fully explained in the film room?

The continued failure to grasp Yankee falls on the players. They've seen it before, Shanahan has the play in his playbook, and it's a concept that isn't difficult to stop.

Week 7– 2nd Quarter, 1st and 10 at the SF 19, 2:36



Oddly, this is not the same play as we discussed above. It was Brandon Cooks catching touchdown late in the second quarter.

Yet again, the deep third of the field was wide open. Second, safety Adrian Colbert dropped so far into coverage, he was 14 yards away from Cooks. He provided zero help on the play.

Never fear! The 49ers double-teamed Cooks, but Cooks already made his break to the end zone. Neither 49er covering Cooks could recover due to their poor positioning. The 49ers had the right coverage called to stop the score, but with no help from the defensive back, the 49ers gifted the Rams six points.

Week 7– 3rd Quarter, 2nd and 10 at the LA 40, 11:00



The play above is also from Shanahan's playbook. At the top, the receivers ran double dig routes. At the bottom, Woods ran an out route while the outside receiver ran a vertical.

Saleh placed the secondary in man coverage, which forced 49ers' defensive back Greg Mabin to cover Robert Woods alone. Except for veteran Richard Sherman, the 49ers do not have the talent or depth to execute man coverage successfully.

Saleh has to use different coverages throughout the game to keep opposing quarterbacks guessing. Man coverage is a gamble for him, again due to the lack of depth on the roster.

Woods is a top ten receiver, and Mabin is nowhere near the top fifty defensive backs in the NFL. Offensive coordinators and quarterbacks beg for a mismatch of this magnitude, so continue to expect it over the next two months.

Week 7– 3rd Quarter, 2nd and 1 at the SF 39, 10:05





In the first shot, I've drawn up the blocking scheme, run, and the defensive alignment.

The second shot was what Gurley saw as he hit the line of scrimmage. It's hard to blame Saleh for the call when both linebackers end up taking themselves out of the play.

Linebacker Reuben Foster overshot the gap by his third read step. Over-pursuit was an issue for him last year, and it appears it has carried over into his second season.

His aggressiveness is a blessing and a curse. Foster will destroy anyone in his path with the force of a 20-ton locomotive traveling at 220 miles per hour.

When he misses, he's far beyond the ball carrier or his gap responsibility, which leads to significant gains.

Foster has no help from Fred Warner who hardly moved but wound up too far inside to make a stop.

There is plenty of blame to pass around 4949 Centennial Boulevard for the 49ers dismal season. Indeed, coaches are not blameless for the team sinking like a stone, and general manager John Lynch shoulders some responsibility for failing to find better back-up talent. Saleh is calling the right coverage, but he's missing the talent to execute even the most straightforward coverage in his playbook.

Everyone deserves a rebound game, and the 49ers need to use Sundays' game against the Arizona Cardinals to hammer away at fundamentals and execution.

    I have a problem with this thinking. Coaches are not just tacticians and motivators. They are also teachers and instructors. If Saleh is making good calls but his guys are all confused and can't execute the gameplan, then it is still HIS fault. I don't believe he can teach or instruct.

    They have enough talent on defense to be ranked in the top half of defenses. One thing I hate about my beloved 49ers, and love about the Patriots is that they game plan every week for their opponent. I know the 9ers game plan. The 49ers don't seem to adjust to the other teams. When the 49ers were up 12 and running pretty well I thought they are going to wear the F out of Arizona with the running game.

    funny, older generations use to say a worker shouldn't balme his tools for a poor jobs. you know that the 49ers are still one of the top guys in cap space right? guys getting hurt should not be an excuse as every team gets injuries. that's why you have guys backing them up. if you draft poorly or don't get free agents why use poor talent as an excuse? Saleh is not a old chilled DC veteran. watch the rams beat arron rodgers yesterday. there is something to be said about experienced dc's. we had a couple, remember guys named Seifret, Carrol, buddy ryan, wade phillips etc...

    When Saleh's D plays teams with comparable talent on O, and today's loss (Sun 10/28) against a ROOKIE COORDINATOR prooves he shouldn't be a DC. This isn't the first year in this system for many of his players, and they can't use the injury excuse as widely painted by the offense. Simple reality: the San Francisco 49ers are not a fundamentally sound team, and this is proven statistically. When it comes to the basics like tackling, communication and understanding assignments this team is consistently lost, not prepared or just plain not in the right spot. It's supposed to be a simple system yet even a rookie OC with a rookie QB can on scheme Saleh. At some point, you have to realize this isn't working Shanahan. Just how far can an entire defense regress? I guess we'll find out.

    Re Marvin Hill: are you serious and your belief that the roster is no better now than it was two years ago? If so, I have to fiercely disagree with you. They have been ravaged by injuries, and they still lack the depth they will eventually need, but from top to bottom the roster is better than what they've had in many years.

    F-Pff, they're not the Be All end all when it comes to statistical analysis. Theyd like you the common bozo to believe that but guess what the Niners are 19th in total Defense 14th in run D and 21st in Pass Defense. So they can slice it however they want to sli6it.This is the same stupid service that will give a guy a less than stellar grade after a multi sack performance. Get real!

Azeez Al-Shaair: Records don't matter when it comes to 49ers-Seahawks

By David Bonilla

No one at the San Francisco 49ers team facility is taking the Seattle Seahawks lightly. On Monday night, the Seahawks lost their third straight and sixth of the last seven games, falling to 3-8 on the season. The 49ers, however, appear to be surging. They have won three straight and four of their last five games. After being cast aside earlier in the season, San Francisco is now entrenched in the playoff hunt. This is 49ers-Seahawks, though. Oddsmakers favor the 6-5 Niners in the road matchup, but Seattle coach Pete Carroll has had 49ers coach Kyle Shanahan's number in recent years. The Seahawks have won the last three meetings between the two teams and four of the previous five. San Francisco's last win in Seattle came during that



Jimmie Ward shares details of 49ers meeting that led to defensive turnaround

By David Bonilla
Nov 17

It looked like a different San Francisco 49ers defensive on the field Monday night against the Los Angeles Rams, especially compared to the embarrassing performance displayed a week earlier against the Arizona Cardinals. The Niners defense held the potent Rams offense to just 10 points in the primetime shellacking. Following the home loss to an injury-plagued Cardinals squad and before the latest game, the defensive captains, which includes Ward, got together to figure out how to turn things around. At 3-5, something needed to change for the 49ers' playoff hopes to remain alive. "We ended up having a meeting with the team captains on defense," safety Jimmie Ward explained on KNBR's Murph & Mac show. "I can't really speak too much on the offense.
