It is a mistake to think top D3 or D2 schools do not require the same time commitment that D1 schools do. NCAA allows 20 hours of practice per week and I don’t know of any coaches who don’t use every single minute. Some D1 teams have more travel, but often is it more luxurious - planes rather than buses!
Effort plays a big part in whether you get to see the field or spend most of the time on the bench.
This is 9th grader. A lot can change in the next 2-3 years.
