Harv and Roy might now the answer to this one, but heard something on a Chicago radio station talking about the state of Illinois and the NCAA tourney. Not sure how accurate this is, but the gist of the story is very telling as you always hear how much basketball talent there is in Illinois.
This year there were no schools from the state of Illinois in the NCAA tourney (there are at least 9 D1 schools too). Despite no Illinois teams in the dance, they were talking about how there were something like 47 kids from the state of Illinois on teams playing in the NCAA tourney.
Never looked at it before, but that is a lot of kids in the tourney from one state that has 9 D1 schools, none of which were in the dance.
