MIT is a bit of an outlier as far as how much weight the coach has to throw around.
At almost all other high academics, D1 and D3, what kind of numbers you need depends A LOT on athletic abilities. I had a coach tell my son that if he was a frosh starter, 27 ACT is probably fine, if he is a developmental guy who may not ever leave the practice room, he probably needed at least a 34, higher is better.
At a different school the coach was a bit more cagey, but when he became the coach’s #1 pick, suddenly the grades and scores ceased to be a problem, and he was told that things had changed, he was no longer on the cusp.
Both of those were Ivy League schools. Schools my son had zero chance at without his sport.
