If you are a "win at all cost" in high school, then this would be ok. I was in this boat at one time in my life. Now, having kids that play, I don't think I'd be real happy if someone from out of state or out of our district came in and took their spot on the team. And as a tax payer too, I'd prefer to support our local kids, whose parents pay for our schools with their taxes, rather than someone outside the district.
I think this will get worse with time. Right now it's just a few kids, but more and more keep trickling down from Omaha or Lincoln into the surrounding areas. More recently I've seen some from medium sized towns like Wahoo, who lost their spots due to Omaha/Lincoln, send their kids to the class C and D schools nearby. So, it isn't just a Class A problem, it will spread out from there.
