The San Francisco 49ers’ 2024 season was a stark contrast to their Super Bowl run in 2023, with injuries decimating what was considered one of the NFL’s most talented rosters. Finishing with a disappointing 6-11 record, the team struggled to maintain consistency as key players were sidelined. As the 2025 season approaches, the 49ers are once again grappling with medical setbacks during training camp, prompting questions about the root cause of their persistent injury woes. According to Matt Barrows of The Athletic, the answer may lie in head coach Kyle Shanahan’s high-intensity coaching style.

A Grueling Approach to Training
Barrows points to Shanahan’s rigorous practice regimen as a potential factor behind the team’s injury issues. “I don’t think there’s any question, however, that the 49ers practice harder and faster than most NFL teams, including in training camp,” Barrows wrote. Shanahan’s philosophy emphasizes preparing players for the speed and physicality of the regular season by pushing them to their limits during the offseason. He aims to build what he calls a “callus” — a mental and physical toughness that equips players to handle the demands of competitive play.
This approach, while effective in some respects, appears to come with a significant downside. The 49ers’ intense training sessions, designed to simulate game-like conditions, may be contributing to the team’s high injury rate. Barrows suggests that the physical toll of these practices could explain why San Francisco faces a disproportionate number of injuries each summer compared to other NFL teams.
The Double-Edged Sword of Intensity
Shanahan’s system is not without merit. The 2023 season serves as a testament to its potential, as the 49ers powered through the playoffs to reach the Super Bowl. The team’s ability to compete at an elite level that year demonstrated the benefits of Shanahan’s emphasis on speed, discipline, and resilience. However, the 2024 season highlighted the risks of this approach. With key players frequently sidelined, the 49ers struggled to field a consistent lineup, ultimately derailing their campaign.
The injury crisis wasn’t limited to backups or role players; it struck at the heart of San Francisco’s star-studded roster. Despite having one of the most talented teams on paper, the 49ers were unable to translate that potential into on-field success due to the constant absence of key contributors. This pattern has raised concerns about whether Shanahan’s demanding practices are sustainable in the long term.
A Team in Transition
Adding to the challenges, the 49ers have lost several key pieces since their 2023 Super Bowl appearance. The departure of impactful players has diminished some of the team’s depth and star power, making it even more critical for the remaining roster to stay healthy. The 2024 season may have exposed a missed opportunity for San Francisco to capitalize on their championship window, but the upcoming 2025 season offers a chance for redemption — provided the team can address its injury concerns.
The Path to a Bounceback
For the 49ers to mount a successful “revenge campaign” in 2025, staying healthy will be paramount. While Shanahan’s high-intensity system has proven capable of producing elite results, it may require adjustments to mitigate the physical toll on players. Balancing the need for toughness with injury prevention could be the key to unlocking the team’s full potential. This might involve reevaluating practice schedules, incorporating more recovery-focused strategies, or leveraging sports science to optimize player health.
The 49ers’ front office and coaching staff will also need to prioritize depth in their roster construction, ensuring that the team can withstand inevitable injuries without derailing the season. While the loss of key players has stung, San Francisco still possesses a core of talented athletes capable of competing at a high level when healthy.
Conclusion
The San Francisco 49ers’ injury struggles have cast a spotlight on Kyle Shanahan’s coaching philosophy, with its emphasis on grueling, high-speed practices. While this approach has yielded success in the past, its role in the team’s recent injury woes cannot be ignored. As the 2025 season looms, the 49ers face a critical juncture. By addressing the underlying causes of their injury issues and making strategic adjustments, San Francisco can position itself for a much-needed bounceback. The talent is there, but the key to unlocking it lies in keeping the roster intact and ready to compete.
