Be careful... People in general will always try to find fault with the winner of a contest, especially if it's a band like Poteet who wins a whole lot.
I remember being at the 2003 State Marching Contest when they didn't even make finals (and everybody thought they would); every band they walked by jeered and yelled at them; I felt really sorry for them. Then, I distinctly remember them sitting in the stands during finals fervently applauding one of those bands that was not nearly so kind to them earlier. I was probably too young to get it then, but looking back on it, that was really awesome.
I'm not saying they didn't do what you say they did; just be sure that you aren't being a sore loser and trying to discredit the winner of a contest.
