I feel the most important statistic in determining who wins a basketball game is rebound margin, i.e. the percent of total number of rebounds in the game. Obviously rebounding is influenced by forcing our opponents to take difficult shots while getting good shots ourselves and leading in turnover margin.

However, over the years if we have gotten 58% of the rebounds in a given game we have won every time. We have finished in first or second place in our league 14/16 years and have been first in rebounding margin 9 of those 16 years and second 3 times.
