I personally give the judges props for not scoring Phantom high just because they are Phantom and they won last year. I think the general consensus among everyone is that Phantom is not on par with their first place finish last year, nor their fourth place finish the year prior for that matter. Ultimately, your opinion of a corps is yours and yours alone. For instance, Santa Clara Vanguard's show last year was one of my favorites of the year, and one of my favorite offerings from SCV in the past few years. It doesn't really matter to me that they ended in 7th. It's always important to remember that corps aren't necessarily ranked from most enjoyable to least enjoyable. For you Phantom's show is just as enjoyable as ever.
Also, if your listening to Phantom's music, you're listening to top six music. It's the visual program that's killing them.
