Sewell’s snap share percentage was 80.0% in 2025. He has a secure role in the Kansas City defense, but the extent of his involvement in the team’s defensive strategy is not clear. A deeper examination of his playing time and the team’s overall defensive approach would provide more insight into his opportunities.

Steve Spagnuolo coordinates a 4-3 zone-heavy defense with a 31.4% blitz rate. This scheme may limit Sewell’s production, as the team’s emphasis on blitzing could impact his ability to make plays on the ball.
