St. Pat's closed for many reasons much of which was linked to the fact that the population that supported Catholic education in the entire city has declined. also the kids who played ball in town wouldn't go there because they had no shot of playing with kids from all over the state (and out of state) that play there. As a result there were no families investing themselves in the school. Not sure but I don't think many siblings of the players they had over the years (Holloway, Harrington, Dalembert, Nardi, Billmeier, Kidd-Gilchrist, Irving, etc.) ever attended St. Pats which wasn't the case prior to Coach Boyle's arrival.
In the 60's The Elizabeth Parochial Grammar School League had 16 teams. These were school, not CYO teams. Growing up within a 10 block walking distance from my house I could go to Sts. Peter & Paul, St.Patrick, St. Adalbert, St. Michael's, St Anthony's or Holy Rosary. Now I think there are 4 (?) Catholic elementary schools open in the whole city. . What I would really like to know is how St. Mary's in Elizabeth stays open.
p.s. From what I heard at St.Pats some of the NBA guys have been very generous, in particular Kyrie Irving. Others have given back nothing.
