Bills' Joe Brady Warns James Cook Over Fumble Issues

By Cameron Tate

Buffalo Bills offensive coordinator Joe Brady has issued a stark warning to running back James Cook III regarding his recent ball security issues. Cook fumbled twice during the Bills' 37-34 overtime victory against the Los Angeles Rams in Week 5, bringing his total to four fumbles over the first five games of the 2026 season.

Brady emphasized the importance of ball security, stating that persistent fumbling could lead to a reduction in Cook's playing time. "At some point there has to be consequences," Brady said, highlighting the need for improvement despite Cook's impressive rushing statistics, which include an average of 106.4 yards per game.

Cook's fumble in overtime against the Rams nearly jeopardized Buffalo's victory, underscoring the critical nature of the issue. With four fumbles, Cook is currently tied with Cam Skattebo for the most fumbles by a non-quarterback this season.

Despite the fumbles, Cook has been a key player for the Bills, participating in 67.3% of the team's snaps and contributing significantly to their offensive efforts. In the Week 5 game alone, he recorded 111 yards and two touchdowns.

While Brady's comments do not immediately threaten Cook's position as the lead back, they indicate a potential shift in his role if the fumbling continues. The situation presents a balancing act for the Bills, who must weigh Cook's productivity against the risk of turnovers.
