One person carrying a ball must "run it straight" at the defender, who is also sprinting towards them: they are not allowed to duck, hurdle or sidestep the tackler. "It's like shaking a baby," says Peter Satterthwaite, whose teenage nephew died after copying the game at a party. "I used to 'run it straight' at Brandon all the time," Hancock says, joking that the pair would usually try to avoid hitting each other straight on. Hancock insists Run It is a "game of skill" - "[It's] all about the footwork" - but there's no denying the violent nature of it. Weeks after Ryan's death, the league posted a video saying the game is "not for the backyard, not for the street".
