D3 is a different animal. Do not expect a written offer from a coach in most cases. They show interest and say how much they like you. There is no real commitment at D3. If you "commit" there is nothing to stop you, (except your word, So it depends how important that is to you) from talking to other schools. You are not officially on the team until you enroll are accepted and show up on campus. The D3 timeline is much different than the other Divisions. If the coach asks you to enroll Early Action (always a good idea.) or Early Decision, that could be considered an offer.
In many cases financial packages do not come out until the school has your fafsa. Many times schools have you fill out a form in addition to a FAFSA. Here is the process as per My son's old school.

We also had to fill out a second form in addition to the FAFSA. However I cannot find that information on their site anymore. It was a long complicated Application we filled out besides the Fafsa.
None of the schools that recruited my son had the coach provide the Financial package. They just asked that we keep them updated.
Edit - Found it. We also had to Fill out the CSS profile.

Looks like my sons school no longer participates.
