This is funny!
Personal experience: MAJOR TALENT and reasonable evidence that player willing to work toward grades will get you in ACC or SEC. The better programs closely monitor grade situation and offer solutions. Son's close friend did not have min.GPA standard or SAT min for his SEC school, coaches brought him up summer before freshman year, he took a few classes, and has worked hard to keep up grades, and he paid off for coaches, he's everyday starter.
Others really have answered question best with stressing the importance of grades, but student that may be average SAT, might work harder to keep up GPA, smart coaches do not want to lose a scholly to grades, don't want to loose a good player to lower standards elsewhere. Kinda common sense, player do your best to give yourself "grade insurance", parent, do your homework on school.
