This year had a fantastic musical program. It was truly exciting to see them do something very challenging this year in terms of speed and demand. People, judges, and especially members/alumni expect that Cadets pull off a tremendously challenging show. The shear attempt to do something hard is actually part of the effect. I don't think a lot of other corps ride on this very specific expectation.
One other expectation is that the Cadets should march very well. For Cadets' historical standards, they have been marching very poorly since 2010. Winning visual performance was never a goal and should never be but upholding a quality standard is critical. I haven't seen them come close 1993, 1997, 1998, 2000, 2003, 2005, 2007-2009.
I don't know why it took such a drop.
