Official Structural Takeaway
While both sports share a pitch-based turf heritage and 19th-century English codification, Football prioritizes foot-to-ball technical manipulation with strict prohibitions against upper-body handling and physical grappling, whereas Rugby Union is built upon controlled ball handling, backward passing, structural scrums, and full-contact tackling.
