The Cardinals’ 2025 opener against the Saints kicks off a jersey-number chronicle for No. 18, tracing who wore it across eras and signaling what it could mean for a potential breakout year. The countdown centers on Harrison Jr. as the latest No. 18, with a nod to past standouts who defined the digit’s legacy. A.J. Green and BJ Ojulari surface in the lore as notable No. 18 wearers, anchoring the number to both wide receiver and edge roles. Historic names and a Hall of Fame reference sprinkle the timeline, while Mulleneaux’s Southern Arizona roots add a local twist. Fantasy watchers are prompted to weigh Harrison Jr.’s upside against the weight of a storied lineage, and to tune into Cards Wire’s Rise Up, See Red for the latest chatter.
