I've identified 20 DI coaches who have ties to Kentucky, either as a high school player, college player or as an assistant coach somewhere in the Bluegrass State. I've probably overlooked a few.
I know there are states with more representatives but I think Kentucky stacks up pretty well with similar sized states.
