The following is not complete, I haven't looked at February, March and most of April, 1945.
First up, December 1944, Cousy was not on his Andrew Jackson High School team. He was playing for a couple of other clubs. In the Christian Youth Organization, the Queens CYO, Senior Division, Gold Section. The team was St. Pascal Baylon of Hollis.
Here he scores 56.
He would lead this team to the Queens County CYO championship, then win the Long island title as well against a squad from Brooklyn. This was even after he did join the high school team, he would play for both. Actually, as we will see, for three teams.
He was playing in the (Long Island) Press-Kiwanis Basketball League, Junior Division, Red Section for the St. Albans Lindens (Linden Boulevard is a main drag through the area, it opened this far east in late 1930s). Here is announcement of his joining the Jackson varsity team
He was not a high scorer with the high school team, they finished 3rd place, winning the consolation game in the Queens P.S.A.L. (Publc School Athletic League). Following the season, the high school players (not just the seniors) formed a team called the East Enders (St. Albans is bordering Nassau County)
La Salle Military Academy is in Oakdale out on Long Island, a prep school, still there today.
