NFL Coaching Tree

An interactive map of the 2026 NFL coaching tree: who trained under whom. Every current head coach, offensive coordinator, and defensive coordinator, traced back through the head coaches they served under, as a 2D/3D force-directed graph with coach photos. Color by founding tree (Shanahan, Parcells, Holmgren...), click any coach for their career, mentors, protégés, record, and Super Bowls. Plus a biggest-trees leaderboard and a methodology tab. Built entirely from Wikipedia, served self-contained from MotherDuck.
