 If you've ever been to a professional football game, you've probably had the same experience. Yeah, you're surrounded by experts at the game. Yeah, those fans, you know, that are on a first-name basis with every player. Yeah, you know them. Actually, the players don't know them. Probably wouldn't admit it if they did. But these fans feel free to call every player by his first name. And, of course, all the people around me seem to know how every play should be made. Yep, occasionally they would cheer. More often, they would criticize.
