NYC Hoops (powered by Rivals.com) ranks the top 10 high school basketball teams in New York State based on wins & loses (league & non-league), taking into account how many games were played and competitive level of teams played. Relative weight, in order, is given to wins or losses against nationally ranked out of state teams, other teams in The NY Top Ten (NYC, Long Island or Westchester/Upstate) and against the 6 "bubbling under" teams. Less weight is given to teams that are not ranked.
Ranking position is updated every Monday unless that Monday is a holiday. Then ranking is updated the following day.
