It's always better to play the game-- to appreciate the sport. Flag-football is an alternative to tackling-- as it uses the same rules, except no helmets and pads. A safer and cheaper alternative to the real thing. Generally, players wear uniforms with a dangling-cloth tied around the hip-- and the object is to pull it off to stop the opposing team from scoring. Still competitive as ever, just a different format. Leagues are gearing toward this type of activity-- to encourage sportsmanship without injury. Kind of like a water-down version of Gatorade, but it will still quince your thirst!
