I know a stud when I see one

“So, on Thursday, six of us brave mothers clutched our coffee cups and tried to appear wakeful. (Well, I was shooting for conscious.) It might have been the artificial alertness inspired by my triple latte – or perhaps the open notebook I’d laid on the desk. But when McLaughlin instructed us to introduce ourselves and identify our sons by number and position, he pointed to me and said, “You first.”

Who knew there’d be a test on the first day? I gulped. For a moment my name eluded me. Good thing I’d written it on my notebook cover. “I’m Cindy, my son is Alex. He’s number 21 and he’s a kicker.”

The other moms followed suit. I think we all passed. When one of the ladies mentioned hesitantly, that her son played OL/LB (that’s offensive line/linebacker for you novices), the coach nodded, “That’s right, he’s a stud.” http://www.spokesman.com/stories/2009/sep/17/grid-clinic-for-moms-an-eye-opener/

Question: How much knowlege of a sport do you really need in order to be able to enjoy watching it?
