American Football Positions Infographic in Retro Bracket Style

Sports infographic titled "American Football Positions". TOURNAMENT BRACKET archetype adapted to the topic: a clean retro 1970s sports print infographic that visually organizes American football positions into bracket-style groupings, while still accurately rendering an American football field to current official proportions as the background, top-down and to scale, in a green pitch and white palette. Editorial sports illustration, vintage print texture, limited ink look, crisp white linework on green field, no real team / league / sponsor logos, no watermarks. Show a regulation American football field with accurate yard lines, hash marks, end zones, midfield stripe, sidelines, and proportional markings based on current official rulebooks. Overlay a bracket structure that classifies positions from broad groups to specific roles: Offense, Defense, Special Teams branching into standard American football positions. Every position node must include a small player icon, an English position label, and a short English role caption. Include positions such as Quarterback, Running Back, Fullback, Wide Receiver, Tight End, Left Tackle, Left Guard, Center, Right Guard, Right Tackle, Defensive Tackle, Defensive End, Linebacker, Cornerback, Safety, Kicker, Punter, Long Snapper, Kick Returner, Punt Returner. Use bracket connectors, subtle iconography, and small inset top-down placement cues on the field where appropriate. Keep the composition clearly a bracket infographic, not a motorsport scene, but maintain polished sports editorial design. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real team / league logos, no watermarks No real team / league / sponsor logos. Field dimensions and rules accurate to current official rulebooks.
