this is not proof at all. how many firms conduct OCI on campus really doesnt have alot to do w/ the quality of the school. there are a number of factors.
by the same way you conducted that cooley is better than roger williams someone could just as easily say that georgetown is better than harvard and gtown is the best school in the country.
there are so many comparisons you could make from this list that would be innaccurate. indiana has 19 oci'ing firms, nc central has 37, that in now way means nc central is better.
different marketplaces. different expectations of graduates. more money spent in career development. yada, yada, yada. there are way too many factors to take into considereation for ranking two schools, than simply oci stats.
