text: Also when you cancel out the kids from activities, such as football, you can lose valuable players and lose and get a bad rep for the team/school. Most of the football players can get C' s easily and still learn the same amount and do the activity. Say the quarterback has a great academic year and passes with A' s all year long. He is obviously smart and capable of work. The next year that same kid is passing with a 79% right below a passing B. He is still the smart kid from last year, but maybe he wanted to step his game up academically and take all honors and he is getting piled up with work. He is still learning fine, but he is receiving to much work so it is lowering his grade. If you change it to a B then he can still play and be satisfied that he gets to because if you take the football away he could get emotionally upset and completely forget his work.
