Why would I complain - it happens in the sport. If you flicked at at my collarbone 10 times in a row I might yip at you in a practice situation to knock it off, but I am choosing to participate in a full-contact sport and I have to take my lumps or not participate. I'm not saying you aren't going to complain that it hurts, but don't yip at me because its not my fault that that you made active choice not to wear something that could, so I'm told, protect you from some of that pain. When I have hit a guy I am always sorry that it happened because it is not my intent to double my opponent over in pain. I'm not aiming for anyones jewels, but its still a guys choice to wear a cup or not, and not my fault when you don't and end up on the floor.
