I was thinking about some of the things the Boks do and do badly like those really annoying shallow kicks. If you cant win in the air then why not stop contesting in the air and have your faster guys gun down the catcher as hard as he can taking him to ground and having a second player come in over the ball. If that wing or whatever player cant get him to ground, hold him up or turn him around in the tackle, or teach your boys to rake tackle (grab the wrist of the opposite arm and rake downwards to dislodge the ball. Use the high kicks to trap the enemy in a congested small area behind the midfield so they cant break out and pressure them to keep possession without conceding penalties. If they concede then you can hoof it into the corner and unleash that powerful maul. I think that makes more sense than leaving acres of space wide behind the rush and looking like you could concede everyyime you kick the ball.
