Differences between competitive day school and boarding school admissions?

I’m following closely since we are hoping our hook for BS is an impact athlete.

My kid is applying to BS and to a local day school. She contacted coaches at every school where she is applying. The BS coaches all zoomed with her. The day school coach came and watched (and freaked kid out because afterwards coach introduced herself to kid. I hadn’t warned kid that coach was going to watch because I didn’t want her to be nervous!)

She has another sport where she would make Varsity as a freshman, but is not expected to make a significant difference to the team. Some coaches zoomed with her, others just sent her contact details of students on the team and let her get on with it.

We only applied to schools with strong teams and coaching in her sport.
It’ll be interesting to see how the cards fall on M10.

Note that we are not in NYC so not dealing with those dynamics.
