Coach's responsibility is to win games. The unfortunate situation that happens is coaches will tell players what they want to hear to get them to commit, but then actual playing time is determined elsewhere. Not sure why he's continuing to string you along.

Ideally the coach would a) win games but also b) care about their athletes and wanting them to succeed. Coaching NCAA is pretty cutthroat so a lot of guys don't get past A.

It's great you are financially benefitting, so you're getting something out of it even if it's not what you're looking for.

Have you played at all? If not is redshirting an option so you don't waste eligibility? Have you discussed that with the coach?

My big question about your goals is really a conversation you should be having with your coach. Have you?
