Training camp in San Francisco took an unexpected turn this week as the 49ers made a strong statement about standards and expectations. The front office wasted no time making tough roster decisions.
Head coach Kyle Shanahan and his staff have set a clear tone: the 49ers’ locker room is reserved for those who buy in—on the field and off. Culture matters as much as performance in Santa Clara.
Word spread quickly on Thursday when two rookie undrafted free agents were released just days into camp, sparking conversation among fans and beat writers. The message was simple: attitude comes first in this building.
Linebacker Stone Blanton, a tackling machine out of Mississippi State, was one of the hopefuls vying for a depth spot. Despite his impressive production in college, adapting to NFL culture proved to be a challenge.
Running back Corey Kiner, a north-south bruiser from Cincinnati, also saw his time in San Francisco cut short. Known for his physicality, Kiner joined the roster with special teams and backup duties in mind.

Team officials clarified the decision, with one staff member noting, “Talent matters, but mindset matters more. We can teach the skills, but here in San Francisco 49ers, the right attitude is a must. If you don’t have it, you don’t fit this team.”
Both rookies flashed potential during early practices, but sources say their approach and professionalism fell short of what Shanahan expects from even the newest faces in the room.
For the rest of the roster, the move is a stark reminder: every player must earn their spot, not only by performance but by embracing the team’s culture and putting the 49ers above all else.
