It's mentioned in the rules, but I cannot believe this decision is in agreement with the spirit of the rule. If applied this way, there could likely be dozens or of schools in TN with ineligible kids, all over the state.
For example, there are no Lincoln County buses that pick up inside the city of Fayetteville to my knowledge, but kids from Fayetteville do now and always have attended LCHS - should every LCHS win in history be forfeited? Many kids who are technically 'zoned' to attend Franklin County HS attend Huntland instead, you just have to provide your own transportation (Though bus routes are separate, you've generally been welcome to attend whichever high school you like in FC, provided you can get there). Good chance every team at Huntland has an ineligible kid now and probably always has had, if bus routes alone govern. There would be a few at FCHS where the opposite is true - Huntland bus runs by their house instead. There's a family with a son in Huntland in athletics and a daughter at FCHS in athletics.
I can't believe that Lincoln County and Franklin County are the only two who would have dozens or hundreds of historical teams who would have to forfeit all games if the bus route rule governs. I'll bet there are dozens and dozens of schools that would be affected. How about Marion Co and SPitt - what are the boundaries and bus routes over there? I have no idea.
I think this has a world more tentacles than anyone at TSSAA realizes at the moment. There might be a big number of playoff teams with ineligible players if this is applied across the board. Tullahoma has no buses, but allows kids from inside Franklin County and outside of Tullahoma to attend. Do they have to abandon athletics?
