Just think how much CT high school basketball would suck without East Catholic, NDWH, ND Catholic Fairfield, Windsor, Northwest Catholic, Saint Bernard School, Sacred Heart Waterbury (now defunct which is a shame) Holy Cross Waterbury, Trinity Catholic Stamford, St. Joseph's Trumbull.
These schools keep top kids in state much better than the publics were doing which to me is much better than seeing all the talent leave to play at boarding schools during the afternoon in front of boring sparse crowds.
