Drift Defence Meaning in Rugby Union

Drift defence is a tactical system where the defensive line moves sideways toward the sideline as a unit. Instead of rushing straight forward, the defenders slide across to cover the space on the edges of the field. The goal is to use the sideline as an extra defender to trap the attacking players in a corner. This strategy is excellent for stopping teams that like to pass the ball wide and run around the outside. It requires the inside defenders to push their teammates outward to ensure no gaps open up in the middle. If done correctly, the attacking team finds themselves running out of grass with nowhere left to go. It is a more patient and calculating style of defending compared to a high-speed rush or blitz. For example, as the ball moves wide, the whole defensive line shifts right to meet the fast wingers. The runners are eventually forced out of bounds by the wall of defenders moving with them. It is a smart use of space.
