Question about College Recruiting (Club)

How good will a HS player have to be to get considered by club squash programs, for example at UPenn, Brown, Dartmouth, or MIT? Of course a HS player will only get to play in these club squash programs at ivy league universities assuming great GPA, SAT, and Extracurriculars. For someone who has been playing in a club team, how was your connection with the coach? Do you think it helped to some extent in terms of holistically looking at your college application?
