My non-recruited athlete daughter was accepted ED, and she had to get their approval to drop a class. This is similar - the preread was based on a particular set of circumstances. If that changes, their answer may change.
And I echo what everyone else said about talking to the coach first, and only talking to admissions directly if the coach directs you to do that.
One of the advantages of being a recruited athlete is you have an advocate at the school who very much wants you to come. Take advantage of that! The alternative is going behind the coaches back, and possibly creating a bad relationship, even if admissions gives you what you want. Pretty much if anything changes at all, you need to be talking to the coach, so there are no surprises.
