As someone living outside MS I can assure this is not true. In the conference they are esteemed much more highly than us. We are thought of as farmer Vandy. They are respected much more because of their recent success.
I too live outside of MS but my experience is opposite of yours. I live in Jacksonville, FL and just the other day had a guy tell me I must be pretty excited about the Trinidad news...I told him I hated it and was hoping that he would be ineligible, and he looked at me completely shocked. I then had to explain that I was Mississippi State and not OM, to which he responded with an "oh yeah, I get yall mixed up all the time" I have been asked about Michigan, Mich State, on OM a lot more than Mississippi state, and this in an strong SEC area (Fl and Ga).
Nobody wants to hear this, but the MS schools are frankly very forgettable once not in spotlight.
