Oral "offers" are worth the paper they are printed on, so it could go like this:
• "we have too many at your position, so you'll not see the field;"
• "admissions says you can't get in;"
• "I'm the new HC, and I think it better you find another option;"
• "You haven't really developed like we thought and you'll never see the field or even make the roster so it's best you not lose a year of eligibility."
The conversation is only limited by your imagination.
