Brock Purdy’s Rising Interception Rate Has Become One of the Biggest Questions Facing the 49ers in 2026
The San Francisco 49ers enter the 2026 season with playoff expectations once again, but one storyline surrounding quarterback Brock Purdy deserves far more attention than it received during the offseason.
Purdy remained productive despite battling injuries throughout the 2025 campaign, yet one aspect of his game took a noticeable step backward.
Turnovers.
For the first time since becoming San Francisco’s starting quarterback, Purdy consistently put the football in harm’s way, raising legitimate questions about whether the increase in interceptions was simply the result of injuries and roster instability or the beginning of a more concerning trend.
The 49ers still believe Purdy is their franchise quarterback, and there is little indication that confidence inside the organization has changed.
However, if San Francisco hopes to return to legitimate Super Bowl contention, reducing costly mistakes will likely become one of Purdy’s most important objectives entering the new season.
Statistically, the difference between Purdy’s earlier seasons and his 2025 campaign was impossible to ignore.
The fourth-year quarterback threw 10 interceptions despite appearing in only nine games.
By comparison, he had thrown just 27 interceptions across his previous 40 games, illustrating how dramatically his ball security changed during an injury-interrupted season.
His interception rate climbed to 3.5 percent, ranking as the fourth-highest among qualified NFL quarterbacks.
Only J.J. McCarthy, Tua Tagovailoa and Geno Smith posted higher interception percentages during the season, placing Purdy in statistical company few franchise quarterbacks hope to join.
For a team built around championship expectations, those numbers naturally attract attention.
Interceptions alone never tell the complete story of quarterback play, but they often reveal patterns involving decision-making, timing and risk tolerance.
Advanced metrics suggest Purdy’s interception total was not simply the result of unfortunate luck.
According to BTB Analytics, Purdy ranked among quarterbacks who combined a high interception-worthy throw rate with a high actual interception rate during the 2025 season.
In other words, many of the interceptions were connected to passes that analytics considered genuinely risky decisions rather than random deflections or unusual circumstances.
That distinction matters because it shifts the discussion away from bad luck and toward quarterback decision-making.
Simply put, Purdy attempted more dangerous throws than he had earlier in his career.
Those choices occasionally resulted in turnovers that placed additional pressure on San Francisco’s offense and defense.
Interestingly, however, the interceptions themselves did not completely derail the 49ers.
San Francisco actually performed surprisingly well in several games where Purdy committed multiple turnovers.
The 49ers finished 2-1 in games during which Purdy threw at least two interceptions.
One of the most remarkable examples came against the Carolina Panthers, when Purdy threw three interceptions yet still helped guide San Francisco to a convincing 20-9 victory.
Overall, the 49ers posted a 4-2 record in games featuring at least one Purdy turnover.
Those results demonstrate that the team remained capable of overcoming mistakes, particularly when the defense and running game continued performing at a high level.
Still, consistently asking the rest of the roster to compensate for quarterback turnovers is rarely a sustainable formula for long-term success.
The playoffs often magnify every possession, making interceptions considerably more damaging than they might appear during the regular season.
That reality explains why reducing turnovers remains such an important objective despite San Francisco’s respectable record in those contests.
Another interesting comparison emerged during Purdy’s injury absence.
Veteran quarterback Mac Jones started eight games while Purdy recovered and quietly produced efficient football.
Jones finished with a 5-3 record while throwing only six interceptions across 289 pass attempts.
His interception rate settled at just 2.1 percent, substantially lower than Purdy’s mark.
BTB Analytics also evaluated Jones much differently from Purdy.
While Jones finished with a league-average interception-worthy throw rate, Purdy consistently attempted passes carrying greater turnover risk.
That does not necessarily mean Jones played better overall than Purdy.
The two quarterbacks possess different strengths, offensive responsibilities and levels of aggressiveness within San Francisco’s system.
However, the comparison illustrates that protecting the football remained possible within the same offensive structure.
For Purdy, the challenge now becomes determining why his decision-making changed so noticeably.
Several factors likely contributed.
The most obvious explanation involves health.
Purdy dealt with injuries throughout much of the season, making it more difficult to consistently execute timing-based throws and move comfortably within the pocket.
Quarterbacks frequently compensate for physical limitations by forcing passes before pressure arrives or attempting more difficult throws than usual.
Those split-second decisions can quickly increase interception totals.
The supporting cast also experienced instability.
San Francisco dealt with injuries throughout the offense, limiting continuity among pass catchers and reducing the margin for error during critical situations.
When receivers miss time or offensive chemistry changes, quarterbacks often become more aggressive in attempting to create plays rather than allowing drives to develop naturally.
The 49ers believe those circumstances should improve considerably entering 2026.
Perhaps the most significant addition is veteran wide receiver Mike Evans, whose combination of size, experience and ball skills gives Purdy another dependable target in contested situations.
Evans has built a reputation throughout his career for winning difficult catches, something that could reduce pressure on Purdy to deliver perfect throws every snap.
San Francisco also strengthened its receiving depth in several other ways.
Christian Kirk brings additional route-running experience and versatility, giving Shanahan another reliable option capable of creating separation underneath and across the middle of the field.
Rookie receiver De’Zhaun Stribling enters the organization after generating significant excitement during the draft process.
The 49ers selected Stribling with the first pick of the second round, believing his combination of size, speed and physicality fits perfectly within Shanahan’s offensive philosophy.
Veteran teammates have already praised Stribling’s willingness to block and his natural athletic ability during offseason workouts.
His development could provide Purdy another valuable option as the season progresses.
Former first-round pick Ricky Pearsall is also expected to assume a larger role after continuing his own development.
The organization remains optimistic that Pearsall’s growth will further diversify the passing attack and reduce defensive attention on San Francisco’s established stars.
Perhaps most importantly, Purdy could once again benefit from having Christian McCaffrey and George Kittle available together within the offense.
Few teams possess a running back and tight end combination capable of influencing defenses the way McCaffrey and Kittle can.
Their presence naturally creates more favorable passing opportunities by forcing opponents to defend multiple threats simultaneously.
A healthier offensive group should theoretically reduce the number of situations where Purdy feels compelled to attempt low-percentage throws into tight coverage.
That could become the single biggest factor in determining whether last season’s interception spike proves temporary.
Still, personnel improvements alone cannot solve every problem.
Purdy must also refine his own decision-making.
Championship-caliber quarterbacks consistently understand when to attack aggressively and when to simply accept a checkdown or throw the football away.
Those seemingly small decisions often separate efficient offenses from turnover-prone ones.
Shanahan’s offense has historically rewarded quarterbacks who remain disciplined while trusting the system to create explosive opportunities naturally.
If Purdy returns to that approach, many of the interception concerns could fade quickly.
The encouraging news for San Francisco is that Purdy has already demonstrated over multiple seasons that protecting the football is one of his strengths.
His earlier body of work carries considerably more weight than one injury-affected season.
That history provides reason for optimism rather than panic.
At the same time, repeating the mistakes from 2025 would inevitably raise more serious questions.
Quarterback performance often determines whether talented rosters reach the Super Bowl or fall short in January.
The 49ers have assembled an offense loaded with proven veterans, emerging young receivers and one of the NFL’s most respected offensive coaching staffs.
The expectation now is that Purdy takes advantage of those improved circumstances.
If the interceptions decline while the explosive plays remain, San Francisco will once again possess one of the league’s most balanced offenses.
If the turnover problems continue despite a healthier supporting cast, however, critics will understandably wonder whether the 2025 season represented something more than an injury-related anomaly.
That makes Purdy’s development one of the defining storylines of the 2026 campaign.
The 49ers do not need him to become a different quarterback.
They simply need him to become the version of Brock Purdy who consistently made smart decisions, protected the football and allowed San Francisco’s talented roster to dictate games.
With improved health, more weapons and another full offseason in Kyle Shanahan’s system, Purdy now has every opportunity to prove that last season’s interception spike was merely a temporary setback rather than the beginning of a troubling pattern.
For a team with Super Bowl ambitions, that answer could ultimately determine just how far the 49ers are capable of going in 2026.
