Marvin Harrison Jr. enters the 2026 season fully healthy after missing time in 2025 with a concussion, appendectomy, and foot issues that limited him to 12 games and four receiving touchdowns. New head coach and play-caller Mike LaFleur has installed him as the primary X-receiver in a scheme modeled on his Rams experience with Davante Adams, emphasizing motion, formations, and red-zone usage that aligns with Harrison’s size and route-running profile. Competition for targets remains significant from tight end Trey McBride and wide receiver Michael Wilson, both of whom posted strong 2025 numbers, while quarterback Jacoby Brissett anchors an offense that supported multiple 1,000-yard receivers last year. Training camp reports highlight consistent production and minor cramping concerns that resolved quickly, positioning Harrison for a potential uptick in scoring opportunities if the Cardinals sustain passing volume.
