It doesn't matter how many times corps A beats corps B in a certain caption, it matters on that nights performance and the judge that happens to be there that night. If the judge never put cavies up then why shocked when he does the same thing finals night?
GE Visual is not based on how clean a corps alone. Part but not all. For that you look to visual ensemble. GE is mainly how well composed the drill is, how well it helps in getting the point of the show across, and how entertaining it is.
True the cavies performed very well last night, but not as well as either the cadets or blue devils. Imho I feel like their drill this year lacked the quality of the years prior.
And yes I was there all three nights
