I thoroughly enjoyed Berry Tramel’s recent traipse into what-if territory as he explored what would have happened to OSU hoops if Eddie Sutton hadn’t been hired and what if Mike Gundy had gone to OU. Another one he did was about Oklahoma State and the Missouri Valley Conference.
What we now know as the Big 12 originated with Missouri, Nebraska, Washington University (St. Louis), Kansas State, Iowa, Drake and Iowa State in the early 1900s and was called the Missouri Valley Conference.
Oklahoma State wouldn’t join the Missouri Valley until 1925. From 1915-1925 it was part of the Southwest Conference along with Southwestern, OU, Arkansas, Baylor, Rice, Texas, Texas A&M, SMU, Phillips (!
