I recently discovered Branson has a prep school, Link Year, and its basketball team has two 7-footers. Looks like they play a pretty good schedule against JC teams from the Midwest, with a few games against D-2 and other prep schools.
The 7-footers are:
Adam Webb -- 7-2, 225, Lakeland, FL
Hayden Koval -- 7-0, 210, Prosper, TX
Have no idea if these guys are any good or if Mizzou is interested, but based on the competition they play, I'm guessing they aren't complete stiffs. Also, guessing there are several other guys on the team who are better than the two "bigs," but size always is hard to find.
Down the road, at least, Tiger fans might want to keep an eye on Link Year. The school seems to be bringing some bball talent into the state. Here is roster:
