Tough to compare NYS titles, since some schools bounce from A to B or B to C. However, just looking at Class B, there have been 30 champions crowned. Section 8 has 11 (Garden City with 5 and South Side, Wantagh, Lynbrook, Bethpage, Manhasset and Elmont with 1 each), Section 1 has 6 (Yorktown), Section 3 has 5 (Jamesville-DeWitt with 4 and Cortland with 1), Section 11 has 5 (Huntington and Comsewogue with 2 each and Rocky Point with 1), Section 5 has 2 (Victor and Canandaigua) and Section 4 has 1 (Corning East).
Agreed, Yorktown doesn't get much support from other Section 1 schools (Mahopac has one A title and Bronxville has one C title), but Yorktown's 7 titles (they won an "A" title when there was only a single bracket) ranks 3rd to only West Genesee (15 A titles) and Ward Melville (8 A titles).
If Yorktown isn't considered dominant or great, then I guess only West Genesee has earned that label. |
