School should be about exploring different things to find out what you are good at and what you want to do in life, but first and foremost, students are in school to get an education. The last time I checked these kids, college included, were "Student Athletes", not just athletes. If that how you helped pay for your education, and by some miracle you make it to be a professional athlete, good for you. However, athletes tend to have short careers, and most don't make the money that the "superstars" make.
Get an education first. That is something that age, injuries, and failing health can't take from you, and always makes you marketable.
