Daniel- I totally disagree! Sports are a wonderful topic for discussion. They provide a great way to discuss probability, statistics, bias, and other concepts that are highly relevant to skepticism.
Like billions of other people, I love sports, even though I acknowledge the baseline inanity. The SGU spends much more time talking about computer games, Halloween costumes, and science fiction. I often feel like an outsider when they discuss these interests, so it is nice to hear them discuss a form of entertainment that is more familiar to me.
