I don't want to bother anyone with bonehead ignorant questions, so ignore this if you will. But I'm completely unfamiliar with the rules. The one that I'd like to know about is: what are you allowed to do to stop the guy with the "ball"?? What stops someone from just running through the field and cramming it in the goal?? I know that this obviously isn't possible, but what does the defense do to stop it?? My instinct would be to run over to the guy and [while ducking the stick] just knock him down. I assume that isn't allowed either [I had a similar problem with the rules in a pick-up soccer game once---much screaming and hollering resulted].
