Of the seven major conference champs(American, ACC, Big 12, Big East, Big Ten, Pac-12, and SEC), how many make the Elite Eight each year?
but thats not a good measure, perhaps better is:
% of schools with a conference champ vs % of schools that have reached the Elite Eight.
I could be quite wrong, but I think living in B12 country has skewed our perceptions (maye even I am over compensating for it).
