actually, they have to do the formations and TRUST ME it takes MONTHS to get them PERFECT and that's not even the FULL marching band that's only about 1/2 of it
It's also really just their style. They are not a competition band. It takes a lot of practice to do what they do. This was also just the type of show they had for that game that year. Not all marching bands march the entire time they're playing.
