This is a great topic to be discussed seriously. At the championship game the ritualized cheers were shouted out with great lustiness by both Michigan and Louisville. They both knew their fight songs and sang them lustily. I didn't even know we had a fight song for years, and no one sings it. After the game the Louisville fans called out something like "C A R D S" and something else after it, and you could hear it echoing around the Dome. I felt envious of both teams. The tedious "Let's... go ... S ...U" chant led by the cheerleaders is death.
The insistence upon playing commercials is also death to enthusiasm. The time outs are too long, too plentiful and then when you want to cheer, they're advertising Aspen Dental in the Dome. If there's a really great play just before a TO, for instance, often many of the fans rise to their seats and start cheering and clapping. We're excited! But then the commercials start, and we then slowly sit down and the excitement wanes. I am getting ticked off writing this!
