Benn Stancil over at Mode did some research and compiled an interactive map that shows where every current D1 football player came from. You can filter the interactive map by conference, school, or position here. You can also read Benn's original post. He also took the data he gathered and made a list showing the geographic diversity of each program's roster which I referenced below. (He based diversity on how many states are represented on each team and how many players come from each state.) Its all really great stuff, so check out the interactive map and read the article.
For a comparison see the map of the universe of college football players.:
Takeaways: As you would probably guess FSU's roster is composed almost exclusively of players from the state of Florida, with Georgia also producing several players and a handful of others that come mostly from the deep south and Texas. Interestingly enough is that while our chief rival UF also almost exclusively relies on talent from within the state they seem to(outside of the state of Georgia) have much less of a presence than FSU(and from what I expected) in SEC country, i.e. the deep south. Regarding geographical diversity it seems that most of what would be considered the top programs, with the exception FSU, rate somewhere near the upper middle of the list in terms of geographical diversity suggesting they do a good job of locking down much of the local talent but they also have a broad national recruiting appeal. FSU might be in a more unique geographical position than other top programs in that the state of Florida has so much talent that it seems you can build a top notch squad by focusing on being the instate recruiting hegemony, landing the plurality of top talent from within the state and only relying on a hand full of out of state players to supplement that talent.
