One of the best, if not the best pregame rituals in all of sports is the Haka performed by the New Zealand rugby team. The intensity on the players face show just how much this ritual means. That is why when they asked Dwight Howard to join them at the Adidas Eurocamp he must have been honored. Watch as the slam dunk champ puts his all into it.
Now watch the All Blacks perform it before a World Cup match. Impressive.
