We had the exact same thing happen this year. I'm sick of the jock mentality and having to fight that tooth and nail. All because of an 0-10 football team also.
BTW... before we made the SMBC I was called in and basically blamed for the 0-7 start to the year. I just loved sitting in the last few pep rallies and making them all listen to acknowledgment of our marching season.
I don't have a clue to how address it other than just go work with the kids that choose to be there with you. They want to work for the program so teach them. Forget the other losers that want to sabotage your program. Easy to say, I know, because you put so much of yourself in it.
