I don't think anyone ever said it "wasn't" a good conference. We were just saying that not every team in the SEC is good. When South Carolina and Mizzoun fans chant SEC, they really should just shut up.
They're good at the top but they're also bad at the bottom just like any other league. The main thing that separates the SEC is that they're a little better at the top than the other conferences.
It's just annoying when these people chant SEC when the team they root for is average.
