Not an athlete parent but if it was my kid I would punt MIT unless he’s not concerned with soccer.
Doesn’t sound like the kind of coach he would want to play for.
I agree it sounds like Cal Tech is done.
Love the one that loves you. From a soccer POV at least MIT would be far down my list. If he decides Cal Tech isn’t for him, find another school with a coach that shows love, even if it’s not at an equivalent academic level.
