💰🏃🏽‍♂️ on Instagram: "A running back (RB) in American football is an offensive player in the backfield, primarily responsible for rushing the ball after a handoff, catching passes, and blocking; they need speed, power, agility, and vision to find holes in the defense, with modern RBs often being versatile enough to handle receiving and blocking, blending power (fullback) and speed (halfback/tailback) roles for a balanced attack and unpredictability. #doechasinjaysin"
