If you don’t know the rules of rugby, then this is what a rugby game looks like: 30 men, some tall and thick like trees, some slim and speedy, spend 80 minutes fighting over an odd-shaped ball. They kick it upfield. When it stops on the ground, they all jump on it and fight to capture it. A player puts it under his arm and bursts through the defensive line, fending off tackles with his hand. The ball gets passed quickly from player to player until finally someone flies through the air and plants the ball on the ground. It’s a try! You don’t have to know the rules to enjoy watching a game. But here are a few things that make rugby unique.
