Rugby allows only backward passes, so players must kick ahead to move the ball forward.

The longer version

The law says a player may only throw the ball to a teammate who is level with or behind them relative to the opponent's goal line. Passing forward is punished with a scrum, so advancing by hand is impossible, and teams must run, kick ahead, or drive forward in a grouped maul. The restriction shapes the entire geometry of attack.

Whether a pass went forward is judged by the ball's motion relative to the ground, not by where the receiver stood, which is why a flat pass caught by a sprinting player looks illegal but is often legal. Momentum decides it, not intent. Kicking ahead therefore becomes a tactical tool: territory is taken with the foot and then contested in the air or at a line-out.
