I have played and watched many rugby games,,
there are many rules and the referee is always right no matter how wrong he is,,
you might be confused by one aspect,,
penalties are not enforce if it doesnt advance the offending teams,,
punching is legal is certain cases but beware the payback from the other team if you take it to far,,
rugby is a savage game played by gentlemen and american football is a gentlemens game played by savages,,
give blood play rugby,,
the little helmets or tape around the head is to keep your ears from getting torn off,,
I watched a big black guy at a tournament getting half his ear sewn back on because he had to play the next game and another guy walk over to the sideline to get a finger reset and taped, he had to stay on the field while the game was continuing or he would have been disqualified
ask me any question you would like and I will try and explain any confusion,,
