Just to add stats for the Big 8's sake;
Kansas, Iowa, Washington U (St. Louis), Nebraska and Missouri were the charter Big 8 members in 1907. Iowa left after a few years, Drake joined in 1908 along with Iowa State. Grinnell College was in from 1918-1928 and Drake left the same year. Kansas State joined in 1913. OU was 1919 as mentioned before. Oklahoma A@M was in from 1925-1928 but left for the Missouri Valley Conference I believe. They didn't rejoin the Big 8(Big 7 at the time) until 1957. Colorado joined in 1947.
Couple notes to point out, 1928 was a big year as Washington U, Drake, Grinnell and Ok A@M all left.
With Missouri leaving this year, that make Kansas the oldest member and only founder left of the original conference.
