Good point Jason. I'm with you on accepting responsibility for oneself and what could happen. However, that is based on a trust that your opponent is a good sportsman and will obey the official and observe the rules of engagement (releasing when a verbal or physical tap takes place-heeding the officials verbal and physical commands). In the case of Drwal-that didn't happen. Hey, I get dinged up all the time. One of my students wanted to roll gi last night (don't laugh!) and tried a collar choke on me by tackling me and basically puncing me in the throat, then putting 200 lbs on my Adam's apple. After I bent both his arms the wrong way, he got the point (I'm exaggerating a little and it wasn't malicious, he understood and we're cool, he's a good kid).
By the way, I hadn't realized how much easier everything is in a gi as I haven't worn one in eons. No wonder the "other guys" like em-you can grab so much easier! LOL!!
