Do you have any band kids that come to school because of band and accidentally get an education? I did. I had a bunch that hated school but because they wanted to perform they went to class and did their work. Do you think any of those football players only show up because they want to play football? And that relationship with those coaches might be the only positive influences the kid has and just maybe, his life will be better later on because he came to school just to play football, (as you put it).....
Stop judging people who are different than you!
