Not sure how much Mahoney's game and shot mechanics have progressed, but after doing some digging it looks like Albany Academy has a legit top-flight program in the area (Section 2 / upstate NY north of Newburgh and east of Utica-ish?) in which they must recruit talent and then compete for titles as they have won the NYS Federation Title as recently as 2016 and I believe went to the final in 2017 (won the Class A, but lost the AA title to Long Island Lutheran?) on the strength of that Wright kid mentioned above, Mahoney and one other strong D1 level player.
So could be that this kid is coming into his own and expanding his game. I'll keep digging. We shall see.
ETA: Mahoney was on the All-Tourney Team which includes potential players from downstate / NYC teams:
All-Tournament Team
Gerald Drumgoole, Irondequoit
Brandon Abrams, Monsignor Farrell
Louis Florimon, Walton Campus
Derek Smith, Walton Campus
August Mahoney, Albany Academy
MVP Hameir Wright, Albany Academy
Also, looking at their 2017/18 sked, it is a damn good sked in which they play every big school in upstate NY along with some downstate schools including the defending LI Lutheran defending champs twice, and a national Xmas Tourney down in Myrtle Beach. Interesting. Might have to keep an eye on this kid. He's only a junior.
