Whenever I see athletes/football players like Brashard Smith, I say they run like a muscle car. Just runs hard and when they get fast its aggressively fast. Accelerates into green. Those are the types of players you need to play big boy football. They just get to the edge ahead of everyone, accelerate into green space tracking a football and then cutting and out running angles up a sideline. Just a little more suddenness, aggression, and intent than everyone else.
Different player, but DeeJay Dallas ran like that sometimes. Runs like he's yelling the whole time.
