It should be mandatory for student athletes to get good grades to play in their sports.
Fallback
Even if you are good at sports you will want to have a fallback. Most student athlete never reach pro level, if they slack off in school and don’t make it to pro it will make it hard to get a good job (According to avoca37.org) “if a student athlete graduating from high school relies on sports, does not pay attention in school, and does not get scouted for a sport, they would not do well in college.” Last If they don't have a good education which leads to a horrible job student loans will be impossible to pay off. Leaving them in a state of debt.
Money
Getting money will be a problem. (According to www.ncaa.org)
