Let me preface by saying I agree that you guys sound loud and the musical talent of the band is second to none. However, the casual football fan can't tell a difference between how loud and awesome the Green Brigade sound and how loud and awesome most any other college band sounds. And generally, they don't care how precisely the music is played, so long as it's loud.
The fans don't go to a band concert and football game just so happens to be played at the same time and place. The pageantry of the band, and their performance in pre-game, in the stands, and at halftime, is part of what makes game-day, game-day.
That being said, some extra pageantry and spirit would only seem to further your lead as the best band in the country. And, it would help make game-day a more enjoyable experience for the fans that are there for the football game, and not the band concert.
