re: What has Missouri ever accomplished of note in Football?

They dislike Mizzou because its new and to many fans of the SEC anything new is suspected of communism for at least 50 years or so.

Making the SECCG in your second year is impressive, it took Arkansas till our third year to get in. Making that game, when you did, allows you certain bragging rights over other schools. Much like we can hold the fact we got into the Championship game much sooner then USC Mizzou can now sit back and enjoy the knowledge that for years to come you can troll the Aggies that you got there first.

You can also sneer at Ole Miss for never having gone. Sneering at Vandy is a social faux pas and Kentucky won't bother to read any taunts directed to their football team because they will be gearing up for another title run in basketball, so you are pretty well limited to taunting the RebelBlackBears.

Enjoy your stay in the SEC and remember, if you weren't doing something right, then they wouldn't be constantly talking about how they ignore you. Its sort of like a five year old throwing rocks at a pretty girl to express affection.
