No, I don't care.
They can scream all they want about how overrated the SEC is. We've won the last 7 titles, have a pretty good chance to make it 8, and no one really disputes it's still the best conference in the country. Missouri won't change that one way or another, just as Texas A&M beating Bama didn't change anything.
I don't think to myself, 'Only __ teams have made the SECCG and we are one of them,' and smile. It's cool that we went and I loved it at the time, but I'm not hanging my hat on anything we did 15 years ago.
