T.J. Edwards played just 8 games in 2025 and Chicago still allowed 127.1 rushing yards per game with him. Without him, that number climbed 7.4 more. Now Edmunds, Byard, and Brisker are gone. One number explains what the Bears are really risking in 2026.

The Chicago Bears know that championships are rarely built on highlight plays alone. While explosive offenses and star quarterbacks often dominate headlines, the foundation of any successful NFL team is usually a defense capable of stopping the run, controlling the line of scrimmage, and forcing opponents into difficult situations.

As the Bears prepare for the 2026 season, one question continues to surface among analysts and fans alike:

Can Chicago’s defense withstand another year of significant personnel changes?

That discussion begins with linebacker T.J. Edwards, whose importance extends well beyond the traditional stat sheet.

When Edwards was available, he provided leadership, communication, and consistency in the middle of the defense. Even though injuries limited his availability during the 2025 campaign, his presence remained noticeable whenever he was on the field.

According to the scenario being discussed, Chicago allowed an average of 127.1 rushing yards per game with Edwards in the lineup. Without him, that figure increased by another 7.4 yards per game.

At first glance, that difference may not appear overwhelming.

Over the course of an NFL season, however, small changes often become the deciding factor between winning and losing.

Seven extra rushing yards every game can translate into additional first downs.

Additional first downs extend drives.

Longer drives keep opposing offenses on the field while wearing down defensive linemen.

Eventually, those seemingly minor gains begin affecting time of possession, field position, and fourth-quarter performance.

That is why coaches frequently focus on efficiency rather than spectacular statistics.

Every successful running play places pressure on a defense.

Every missed tackle creates another opportunity for an offense to establish rhythm.

For Chicago, the concern extends beyond Edwards himself.

The defensive unit entering 2026 looks noticeably different than it did one year earlier.

Veteran leadership has changed.

Several experienced contributors are no longer part of the roster.

Each departure represents more than just another name removed from the depth chart.

Every veteran leaves behind communication, chemistry, and institutional knowledge that cannot always be replaced immediately.

Linebackers depend heavily on trust.

Safeties rely on precise communication before the snap.

Defensive backs must recognize offensive formations within seconds.

Those responsibilities become significantly more challenging when multiple experienced players leave during the same offseason.

That reality explains why Edwards’ role becomes increasingly important.

Inside linebackers often serve as the quarterbacks of a defense.

They organize alignments.

They adjust responsibilities before the snap.

They recognize offensive tendencies.

Most importantly, they help ensure every defender understands his assignment.

When that leadership is unavailable, mistakes become more likely.

Those mistakes rarely appear dramatic.

Sometimes a linebacker fills the wrong gap.

Sometimes a safety arrives one step late.

Sometimes pursuit angles break down.

Individually, those errors seem minor.

Collectively, they determine whether a defense consistently stops the run.

Chicago’s coaching staff undoubtedly understands this challenge.

Preparing for a new season involves far more than replacing individual production.

The Bears must also rebuild communication between every level of the defense.

Defensive linemen must work together with linebackers.

Linebackers must coordinate with safeties.

Cornerbacks must trust that interior defenders will force runners toward the outside.

Successful defenses operate as a single unit.

One weak link affects everyone.

That is why continuity matters.

Training camp provides valuable opportunities to develop chemistry, but real-game situations often reveal communication issues that practices cannot fully replicate.

The Bears will likely spend considerable time emphasizing fundamentals.

Gap discipline.

Tackling technique.

Pre-snap communication.

Run fits.

These details rarely receive national attention, yet they often determine defensive success throughout a long season.

Stopping the run has become increasingly important across today’s NFL.

Although passing offenses continue evolving, playoff football consistently rewards teams capable of controlling physical matchups.

When opponents establish the running game, they gain flexibility.

Play-action becomes more effective.

Third-down situations become shorter.

Quarterbacks operate with less pressure.

Conversely, defenses that consistently stop the run force offenses into predictable passing situations.

That advantage allows pass rushers to attack aggressively while defensive backs anticipate deeper routes.

Everything begins with first down.

For that reason, Edwards’ health and availability could prove critical throughout the season.

Statistics tell only part of his value.

Leadership cannot be measured entirely through tackles.

Communication rarely appears in box scores.

Positioning often prevents big plays before they happen.

Veteran linebackers understand these hidden responsibilities better than anyone.

Fans naturally focus on interceptions, sacks, and forced fumbles.

Coaches frequently study entirely different plays.

Did the linebacker fill the correct gap?

Did the safety rotate properly?

Did defenders maintain leverage?

Did everyone execute their assignment?

Winning defenses consistently answer “yes.”

The Bears also face another challenge.

Replacing veteran experience with younger talent often requires patience.

Young players possess athletic ability.

They bring energy and enthusiasm.

Yet NFL offenses quickly exploit inexperience.

Recognizing formations.

Reading blocking schemes.

Adjusting to motion before the snap.

These skills develop through repetition and experience.

That makes veteran leadership even more valuable.

As the 2026 season approaches, expectations surrounding Chicago remain cautiously optimistic.

The organization has invested in building a competitive roster.

Young talent continues developing.

Coaches believe improvement remains possible.

However, every successful season ultimately depends upon execution.

If the Bears hope to become one of the league’s better defensive teams, stopping the run will remain essential.

The numbers discussed entering the season serve as a reminder rather than a prediction.

Small statistical differences often signal larger underlying issues.

Whether Chicago improves against the run will depend on health, communication, disciplined execution, and the ability of new contributors to step confidently into expanded roles.

For T.J. Edwards, the challenge extends beyond individual performance.

His influence reaches every level of the defense.

If he remains healthy and performs at his usual standard, Chicago gains far more than another productive linebacker.

The Bears gain stability.

They gain leadership.

They gain a player capable of organizing one of football’s most demanding defensive positions.

As training camp progresses and the regular season draws closer, one statistic may continue attracting attention.

Not because it guarantees success or failure.

But because it reminds everyone how thin the margin can be in the NFL.

Sometimes the difference between a playoff contender and a disappointing season is not an explosive touchdown or a dramatic interception.

Sometimes it is simply preventing one more running play from becoming seven extra yards.
