There are plenty of highly rated players from the NY area who plays in other conferences.
According to
https://future150.com there were six top 100 players from NY in 2018.
Moses Brown (#22 UCLA) and Isaiah Mucius (#38 WF), Cormac Ryan (#55, Stanford, nerd), Sidney Wilson (#68, SJU briefly), Markquis Nowell (#86, Little Rock, no really, Little Rock) and Khalid Moore to (#98 G Tech.)
In 2019 Cole Anthony, my Precious, Jalen Lecque (NC St), and Aidan Igiehon (to the Louisville Hookers) are in the top 50.
I don't know which of those guys you think the staff didn't recruit or why you'd think they'd consider SJU, but the answers are none and a couple.
Point is regardless of whether the players are from NY or Texas, the staffs presence on the recruiting trail has been minimal and that is common knowledge.
I don't believe in common knowledge. In fact I think that all common knowledge is a lie and the louder and more often it's repeated the more false it is and that's especially true regarding fan board rumors from desperate for attention alleged program insiders.
