Not sure exactly what information or thoughts you are looking for, but if you look at schools in South Carolina you will not see that many South Carolina kids on rosters:
1. USC is the best team in the state and they only have 6 kids from this state. The rest of the team is mostly from region III and then small amounts from mostly the east coast.
2. On the other hand, Winthrop has only 3 kids from South Carolina and a pretty diverse roster otherwise. They really struggled for the most part, but had some decent wins along the way to a poor season.
3. South Carolina State has almost no one from South Carolina mostly due to the fact that hardly any decent player from this state wants to go there. They have mostly California, Canadian, and island players and do better then a Winthrop or Wofford.
4. NCAA Division II Newberry has 10 South Carolina players on the roster and made the tournament this year in problably the second hardest D2 conference in the country.
What does this all tell us? Perhaps not enough quality South Carolina Division 1 players or do colleges simply ignore players from their own state. Some thoughts....
