My home county is grey but I know for a fact that isn't true. Tate Leavitt who I think will be joining the Cats played for my High School's rival, I know 1 person from my hometown who played for the Cats recently, another from my high school rivals, and two from my high school who play/played for WVU.
It's only players currently listed on Division I rosters on ESPN.com, which has some errors, as noted.
Also, there's only so much information one can gather. For example, I grew up in Lucas County and went to school in Lucas County, but based on my mailing address, I probably would have been grouped as Ottawa County in a list like this.
