is the cheer for the sec no matter what portion of LSU fading?
In a word, yes.
I was raised by my father to have the mantra of always cheering for the SEC no matter what. He still does, I do not. I always used to, until a few years ago.
At one time, the SEC was the goat of NCAA and the Big Ten/Pac 10/Notre Dame/Miami/FSU were the beauty pageant contestants. None of the media gave any thought towards the SEC, so we had to be that way to prove our worth.
Things are not like that anymore. Alabama beat Miami in '93, Tennessee beat FSU in '99, LSU beat OU in '04, and then Florida, LSU, Florida, Bama, Auburn, Bama/LSU all in succession. So in other words, there is no need to prove our worth to the media anymore. They get it.
And a poster on SEC rant said it best. With Bama threatening to win 3 of the last 4, it's not about the SEC anymore. It's about Alabama.
