Going back to the 1977-1978 season, I broke down the rosters by state and country. If a player was listed on the roster, I counted it as a 'player season'. Turns out Oklahoma has contributed more than any other state (almost double 3rd place California). I counted Lashann from the Bahamas rather than the listed Texas because I wanted to and Texas already had enough. Also, I did not exclude redshirts or walk-ons because, while this little endeavor proves I have far too much free time, I am not that detail-oriented.
A few Texas players from Oklahoma that come to mind: Amber Hasenmyer, Dee Smith, Kristi Inman, Fey Meeks, Kala Bowers
A few things that stood out as I went through the rosters: The 5 player seasons from Georgia came from 2 players from Marietta - Celina Rodrigo accounted for 4 of them. Celeste will be the first baller from the Empire State since the 1978-1979 season. Whole lotta Duncanville over the years. Jody was hitting West Texas hard in the 80s and early 90s: Nazareth, Canyon, Fritch, Amarillo, Lubbock...
