Son just received his NLI from a Power-5 school. To our surprise, the scholarship is lower from sophomore through senior year. Only the freshman year the % is the same as the verbal offer. Son asked his college coach, he said it's just the placeholder and we will get the same amount the next few years. Son also asked the other recruit in his class, it's the same deal. Tomorrow is the NLI signing date, should we sign it? Is it normal?
