I take it you didn't go to the Citadel and sleep on a cot for 4 years.
For many kids, after freshman year they want the freedom to party and live like adults so off campus living becomes a part of the equation. There are schools where living off campus is not an attractive or safe proposition.
That includes some pretty good schools like Columbia, Yale and schools just in the wrong real estate zip code vis-a-vis when they were built. That doesn't stop kids applying to Columbia or even Temple.
The St. John's Queens campus is a fairly small young campus that lacks landmark buildings common at some schools that have buildings going back 100 or more years.
As for the hyping of Manhattan, that's a complete crock!
My nephews attended NYU and a niece was uptown just south of Barnard. There was no "campus". They crossed city streets to attend different classes. The 14th street dorms were half mile from the class rooms. While excellent schools, the amount of time and money is limited to attend clubs and other events.
Basketball players who consider St. John's know that Manhattan is safe 30 minutes away on the subway.
Some of you make it sound like players are looking for a resort like environment to attend college. I think that fir most, it's near the bottom of the list.
From what I've heard some schools offer really nice housing for athletes. Just saying, regardless of whether people think it's a good experience to share a small bedroom or not the majority of people I'm pretty sure would opt to have their own bedroom, along with a full fridge/kitchen, living room for a proper TV/entertainment setup, private shower/bathroom (with one other roommate), etc... it's just that many schools simply don't offer that option for freshmen (or up). Does anyone here really think the average athlete would opt to share a small bedroom if given the choice? At my school there were plenty of freshmen who shared a bedroom and then the next year either got their own bedroom or went off-campus. The reverse I never heard of happening (going from a private bedroom to shared).
Anyway, I don't think this issue comes anywhere close to basketball, NIL, etc. for the average basketball player, but if everything else is equal then they'll pick the school with the better dorms, classrooms, facilities, campus life, etc.
