If a family prioritizes their kid playing on a certain football team enough to actually pick up and move, I say it should be allowed. But none of this "Oh, I live with my fake uncle now" stuff. I realize it's probably a sensitive subject to uphold sometimes. Especially if there is a certain education program one school offers, like someone mentioned in Aliquippa... I'm sure that clouds the water a bit (even if it's a common sense observation to most people).
If a family moves, they should absolutely be allowed to play without penalty but the WPIAL decides which families move homes for athletic purposes which is crazy to me.
Living with an uncle or grandma, I still think should be allowed but if they aren't the legal guardian, then ok, I can see that being penalized.
