When you are sitting in the bleachers at Wrigley Field, there is a certain code of rules. While the rules may not always be clear to everyone, there is one that every Chicago Cubs fan knows.
When the opposing team hits a home run, you throw the ball back on the field.
No argument, no excuses. You play by the rules. So why is it that this tradition isn't shown on TV? It's about as common as people singing "root, root root for the CUBBIES" and the W flag waving at the end of the game (if the Cubs actually won).
While I would understand if it was the opposing team network that didn't show this, WGN and Comcast never display this action. I don't necessarily think this is disrespectful to the batter, but more of a loyalty to the Cubs. It is clear that both networks are rooting for the Cubs, have announcers that favor the Cubs, and interview Cubs players and coaches. I don't think displaying this action shows any more bias than the networks already display.
As much as I like to watch the opposing team run the bases, I would rather experience Wrigley Field from home and watch as the proud Chicago fan chucks the ball back on the field as the bleachers cheer.
