Whether or not DSU is "better" people are saying they preferred them. That is telling. It doesn't matter what makes you "better" than them if it's not what people want. I don't think anyone goes to football games for a musical performance.
And really, the complaint isn't about the halftime shows. It's the in-game music, and Boerma sucks compared to Nix. Nix understood the MMB's role, and I'd give the band an assist for the Braylonfest comeback. Boerma, not so much.
