NFL Rumors: Kyle Shanahan Targeting $96M Star to Ease 49ers’ Defensive Struggles

Under the fluorescent glare of Levi’s Stadium, frustration has begun to seep through even the calmest corners of Kyle Shanahan’s sideline. The San Francisco 49ers — once known for suffocating defense and surgical precision — have looked startlingly human in recent weeks. Missed tackles, broken coverages, and a visible lack of pressure have ignited alarm bells across the Bay Area. Now, whispers inside league circles suggest Shanahan has a bold, high-priced solution in mind — one that could cost the franchise up to $96 million but potentially restore its defensive soul.

According to multiple NFL insiders, the 49ers are rumored to be eyeing Chicago Bears’ pass rusher Montez Sweat, a defensive superstar whose physical dominance and relentless motor could instantly transform San Francisco’s struggling front seven. Shanahan, known for aggressive midseason moves, reportedly views Sweat as the kind of game-changer who could recalibrate the team’s defensive identity heading into the back half of the season.

A Defense Losing Its Edge

The 49ers’ defense, long the pride of the franchise, has quietly slipped in efficiency. Ranked near the bottom half of the league in quarterback pressures and sacks over the past month, the unit has failed to close out games in the way that once defined its Super Bowl-caliber identity.

While Nick Bosa continues to attract double-teams, the rest of the line has struggled to generate consistent heat. The loss of veteran leadership following offseason departures has only magnified the issue. Fred Warner and Dre Greenlaw remain elite at linebacker, but the pass rush has looked inconsistent, leaving San Francisco vulnerable against high-powered offenses like Detroit and Philadelphia.

“Something’s off,” one NFC scout said. “They still have talent, but they’ve lost that fear factor. Teams aren’t scared of their front like they used to be.”

Why Montez Sweat Fits the Vision

Shanahan’s reported interest in Sweat isn’t random. The 28-year-old defensive end, currently playing on a four-year, $96 million deal, has quietly been one of the league’s most disruptive forces over the past two seasons. With elite length, quick first-step explosiveness, and an uncanny ability to collapse pockets from the edge, Sweat’s presence would immediately complement Bosa’s skillset — creating the kind of dual-edge nightmare that opposing quarterbacks dread.

Sweat has already racked up over six sacks and double-digit QB hits through the first half of this season. His ability to stop the run and set the edge also aligns perfectly with defensive coordinator Nick Sorensen’s hybrid system, which demands both power and discipline.

“He’s the kind of player who changes everything,” said one AFC personnel executive. “Put him on that 49ers line with Bosa and Armstead, and suddenly every protection call becomes chaos. That’s the missing piece right now.”

A Risky but Calculated Gamble

Of course, adding a $96 million contract to a roster already loaded with star salaries is no small feat. The 49ers are one of the league’s most cap-conscious organizations, balancing massive deals for Christian McCaffrey, Deebo Samuel, Trent Williams, and Warner.

But Shanahan and GM John Lynch have never shied away from bold moves when they see a championship window. The acquisition of McCaffrey in 2022 — considered an expensive gamble at the time — ended up transforming the offense into one of the NFL’s most dynamic units.

“If they think Sweat can do for the defense what McCaffrey did for the offense, they’ll find a way to make it work,” one team insider said. “This front office plays chess, not checkers.”

To make the numbers work, the 49ers could rework or extend existing contracts, or even offload mid-tier veterans to clear room. The team’s willingness to restructure deals in the past suggests financial creativity won’t be a deal-breaker.

The Chicago Connection

For the Bears, the rumors come at a time of internal conflict. Despite investing heavily in Sweat just a year ago, Chicago continues to hover around mediocrity. Trading away a star like him would be controversial — but not unthinkable — for a front office trying to accumulate draft capital for a possible rebuild around rookie quarterback Caleb Williams.

“The Bears have holes everywhere,” one NFC North insider said. “If they can get high-value draft picks for Sweat, they’ll at least consider it. The question is whether the 49ers are desperate enough to meet that price.”

Sweat’s trade value is expected to hover around a first- or second-round pick, depending on how much salary the Bears agree to absorb. For San Francisco, that’s a steep price — but one that might feel justified for a potential Super Bowl push.

The Defensive Decline in Numbers

Statistically, the decline in San Francisco’s defense has been both surprising and alarming. Over the last four games, the 49ers have allowed an average of 26.3 points per game, ranking near the bottom of the league in that span. Their sack rate has dropped by nearly 40% compared to last season’s average, and opposing quarterbacks have enjoyed noticeably cleaner pockets.

Defensive tackle Arik Armstead has battled nagging injuries, and newly signed free agents have yet to make a meaningful impact. Without constant pressure, the 49ers’ secondary — once shielded by a fearsome pass rush — has been exposed, giving up multiple explosive plays in crucial moments.

Simply put: the defense needs a spark.

And that’s exactly what Sweat represents — power, consistency, and intimidation.

Locker Room Reactions and Team Morale

Inside the locker room, players have kept a professional tone about the rumors. Still, a few veterans privately admitted that a move like this could reignite energy in the building.

“Everybody knows we’re not playing up to our standard,” said one defensive starter. “Adding a guy like Sweat? That’d shake the whole room — in a good way. Sometimes one new presence changes the whole vibe.”

Head coach Kyle Shanahan, when asked about potential roster moves, gave his usual measured response:

“We’re always looking for ways to make our team better. That’s part of the job. We’ve got a lot of faith in our guys, but we’re never closed-minded.”

Translation: the door is open.

Social Media and Fan Buzz

The rumor has sent shockwaves across social media. 49ers fans, ever passionate and impatient, are divided between excitement and skepticism.

On X (formerly Twitter), one fan wrote:

“Sweat + Bosa = nightmare fuel for every QB. Pull the trigger, Lynch!”

Another posted:

“Love the idea, but not the price tag. We’re already cap-stretched. Don’t mortgage the future again.”

NFL pundits, too, have weighed in. ESPN’s Adam Schefter noted that “the 49ers are one of several teams exploring impact defenders before the deadline,” while FOX Sports’ Colin Cowherd called the move “classic Shanahan — aggressive, expensive, and probably brilliant.”
