Think about this though... Football doesn't change in high school. Football is football. Same with basketball, volleyball and Ag.
BAND CHANGES DRAMATICALLY in high school and kids are scared of those changes. They need to hear from the High School directors, and former students about it.
All the kids hear is "we're going to be practicing EVERY DAY AFTER SCHOOL? OUTSIDE? IN THE HEAT?" and "I HAVE TO GIVE UP MY WEEKENDS FOR CONTESTS AND FOOTBALL GAMES? BUT I WANTED TO PLAY FOOTBALL?".
You need a voice that understands those things to talk to the kids. Sure the MS BD can, but the HS Directors should be the direct contact for correct information.
