Personally I hope the idea of combining schools never, ever comes to fruition. I love the fact that each team pretty much has a rival and the competition to beat the other is what makes the games so great now. There's not many things better than having the WRH vs JK battles for the right to go to the ship. A lot of those kids know each other and I'm sure lots are actually kin to each other as well. It's just an electric atmosphere at those games. As far as a hypothetical school name I'd say it would be called something simple, like Duplin High or maybe even Duplin Central High.
That being said, I hope JK never wins another game, period.
