This drill is taken from the Western Force site. We wouldn’t be big into drills here, but there is a good emphasis on practical skills in this one.
The 9 has to dig the ball out of the tyre, replicating bad ruck ball.
The runner can alter his line, pace and timing of the run.
The player assigned to clear-out the ball carrier can focus on hitting the target with strong technique, getting lower than the opposing player and ensuring proper foot placement.
The tyre is very clever and should provide something fresh for all players involved. Small changes make a big difference.
