It’s possible to get the full ride at a D2 school, but it is a ‘build your own sundae’ production. My daughter did. The two biggest parts of her package were her merit award and her athletic award, which basically covered her tuition and fee . Then she had a state merit award (bright futures) and a resident grant. She also had 3 state/federal need based grants. Those covered her r&b for the first two years. After that she moved off campus and still received a meal plan but did pay her own rent. If she had chosen to stay in the dorm, everything would have been covered.
This only worked because she stayed instate and could use the state grants. Other kids on the team from OOS don’t have the same things covered. Some kids don’t get as much in merit money. It’s all very complicated. That’s for our team and some of the other school teams (basketball, volleyball, etc) might be better funded and those kids, with merit scholarships, may be at full COA.
There are D1 basketball schools that are much lower ranked (academically and athletically) and @actiskillingme son may not want to go to them, but they are out there. Daughter has some D1 choices that with merit and athletic money would have been close to full tuition, fees, room and board. She also had some D3 options that with her low EFC most everything would have been covered.
