Ah, the argument that never dies...
I'm not sure what it was in the other classes, but for four years in 3-2-1A Regional coaches meetings, Dual State always had tons more support than than Grand State. As much discussion as there is on the forum I don't think it's ever going to happen.
It's not a direction KSHSAA wants to go, it's not a direction most school administrators want to go, and the feeling I always had from coaches as a whole was is was not their direction, either. Sure it's a fan favorite, which is obvious here, but the three groups mentioned above are the ones who's final opinion matters most.
