Since the D1 athletic "scholarships" are almost always 1/4 scholarships, they don't help that much with costs (but every little bit helps). The real "payoff" for lacrosse is being able to get into a college you would be unable to get into based solely on your grades and other extracurricular activities. The best case is getting into a great D1 academic school that also plays lacrosse. After that, you need to decide if playing D1 at a lower academic school is better than D3 at a great academic school. (Is 4 years playing lacrosse more important than a top education?).
