It's not that simple at all. Kansas City is much close to KU than Missouri. St. Louis is about as close to Campaign as it is to Columbia. Just because Illinois and Kansas aren't in state teams, doesn't mean Missouri doesn't have to compete with them.
Indiana is also surrounded by talent rich states in Ohio, Michigan and Illinois. Where as Missouri has Illinois, Iowa, Arkansas and Kansas around it. I don't see how you can argue that Mizzou is in a better recruiting area.
We're almost in a better recruiting position than Missouri in regards to geography being closer to Minneapolis, Milwaukee, and Chicago.
