Some coaches can, some can’t. It might depend on the sport and how long the coach has been at the school. At my daughter’s school (STEM, with a high admission rate), the coach was new and didn’t have a clue on which students would be accepted to engineering or chemistry. The ‘pre-read’ was very simple and they got back to the coach that a recruit was likely to be admitted based on an unofficial transcript with the ACT score on it. Two years in a recruit announced she was committed, but didn’t get accepted academically. I don’t think the coach had enough experience to know that by looking at a questionnaire with minimal academic stats. I think a Yale or Brown coach might be very good at it, especially if he’s been there 10 years.
You might be able to get the pre-read but still not have to apply ED
