Why do international rugby union teams keep booting the ball back to one another? Why not kick for touch or keep possession by running the ball instead? Ping Pong kicking is boring.
Because they've not learnt what works ? Gaining distance is useful, especially when it clears a danger for your own line, but I have sympathy with your point of view. When booted for the opposition's defence to catch, it tends to be just giving them the chance to advance/attack. Valid if you can get to him as he catches it maybe, but usually a disappointment.
There are strong rules against attacking a player catching a ball, which makes those chasing the kick cautious, and therefore makes today's rugby even more dull.
Also in reply to previous answers kicking directly for touch is only allowed from certain parts of the field i.e behind the 22m line.However if the ball is put back into the "22" kicking directly for touch is not allowed thus giving rise to "ping pong" kicking.
