"Historically" dinosaurs roamed the Earth too. Going back and counting all-time NCAA appearances is in the same range of relevance as SEC championships.
Over the last FIVE YEARS, the SEC and Big XII are faring about the same in the postseason. 15% of the 40 Elite Eight teams during that time frame have been from the SEC vs. 10% from the Big XII. 12.5% of the 80 Sweet Sixteen teams have been from Big XII over the last five years vs. 10% from the SEC. (BTW, the percentages for the ACC are, respectively, 32.5% and 26.25%.)
I'm not defending the Big XII except for that last data point; should that continue, the "equal" argument will be in question. If you wanna be seen as the same level as the Big XII, knock yourself out. Both conferences are essentially Snow White and the dwarfs, and they deserve little respect in the world of college basketball.
I'm not even sure the Big XII will be here a decade from now. You may want to strive for a higher goal as a conference.
"Elite program," my a$$...
