text: Playing sports in school entices kids to go to school for the chance to play on the team. Many kids only go to school because they can play sports, and they know that if they stay in school and are good enough at their sport, they might get a chance to play at the collegiate level, and maybe even the professional level. Those kinds of kids don't really care too much about their grade, and playing sports makes school bearable for those kids. If they had to maintain a B average, most kids would drop out of school at the first chance they got, not try harder.
