I think that Missouri would rather have the cash that being in the Big 10 would bring for all sports over the recruiting in today's economy. I lived in StL for a while and they relate much more there with Illinois, Iowa & the other 'Midwest states' than they do the schools in Colorado, Nebraska and Texas. With the exception of the University of Kansas, they are much more interested in Illinois, Ohio State, Michigan, etc. Plus the dollars that the schools in the Big 10 make is reason enough.
I think the Big 10 will be:
East: Ohio State, Penn State, Michigan, Michigan State, Rutgers, Purdue & Indiana
West: Missouri, Iowa, Minnesota, Illinois, Northwestern, Notre Dame, & Wisconsin
Not a bad line-up.
Of course of this happens, dominos will fall!
