Let’s talk for a second about in-state opponents.
The reality of the situation is that Mizzou doesn’t really have any. Before any UMKC fans jump down my throat about the Kim Anderson hoops era, however, let’s at least acknowledge that there’s not one Division I school that can challenge Mizzou in a variety of sports. Missouri State can hang with Mizzou in baseball and has a pretty stellar women’s hoops program. Saint Louis has been a better men’s hoops program more recently. SEMO... well, I’m sure they’re great at something.
However, there does appear to be quite a bit of animosity thrown at Mizzou from some of its smaller in-state.
