No you're right. You don't have to play basketball to know basketball, but it sure helps. Like that last sequence, it's hard to know what's really going on in the huddle and what coach is telling you if you haven't actually heard a coach tell you anything.
I think it'd be hard to know what the coach was saying if you weren't in that particular huddle.
How the the hell does it matter if you've been in a huddle before? Doesn't mean you know what's said in every huddle. My God.
