Post-baccalaureate study scholarships are unrelated to sports scholarships. Law is a post bachelor degree. “Buying” your way into a top law school is possible but basically entails buying your way through an undergraduate degree as well which means that you might have “bought” your way in but you’re still ultimately incredibly well prepared. And these people who buy their way in subsidize the exact people you’re concerned about being kept out: poor but well qualified candidates who can become “great” lawyers.
