No need for our schools to 'prove' anything to anyone as far as I am concerned.
But if a relaxed atmosphere could be allowed during the IHSAA regular season, for those schools who have the opportunity to do so...They should be allowed to play outside of a 300 mile radius.
I can assure you, the number of schools would be minimal; Due to expenses, travel, focus on education....etc.
Postseason or otherwise (National Championship) aspirations are not, nor should be the purpose of IN schools. Let others rank and pontificate on that.
