Yes it is because Rugby doesn't have any tackle count, You keep the ball as long as you don't make a mistake. Kicking downfield isn't just something to do at the end of the tackle count, it is more strategic, try to compare with forcings back. The idea is to force the other team to eventually kick for touch and hopefully you will have a lineout and get the ball back further down field than when you started. Rugby has more strategy and planning than League, ie, zombie football
5 tackles, kick, 5 tackles, kick, 5 tackles, oooo mistake, try, kick off, 5 tackles, kick, 5 tackles, kick etc. Rugby is a more fluid game of changing defence and attack strategies.
And no I am not off topic........I added the word zombie.
LOL
How can the bible even mention NZ, it predates the discovery of NZ, Australia and even Nth and Sth America.
