A couple sites I use a lot:
82games.com
basketball-reference.com
Google APBRmetrics too.
As Schadenfreude points out, if you ran through those same games you'd probably find that the team with more defensive rebounds also held the opponent to a lower shooting percentage. The single most important stat is efg differential -- the team that shoots best from the floor wins about 80% of the time in the NBA.
For the original poster -- there are 4 key factors that decide winning and losing. Shooting, ball handling, rebounding and fouls. The factors are not equally important. Losing one (or more) does not mean losing the game -- a team can make up for poor shooting, for example, by getting to the ft line, not committing turnovers and by getting offensive rebounds.
These categories are measured as follows by most of us basketball stat goobers:
- shooting -- effective field goal percentage -- (fg + .5 x 3fg) / fga
- turnovers -- turnover percentage -- tov / possessions
- rebounding -- rebounding percentage -- for this we usually just use offensive rebounding percentages calculated by oreb / (oreb + opponent dreb). Do the reverse to get opponent offensive rebounding percentage.
- fouling -- free throws made / fga -- For whatever reason, getting to the FT line actually shows up as more important than making the free throws, but we still use FTs made as a measure of efficiency from the line.
In terms of general importance to winning, efg differential is a 10, turnovers about a 5-6, rebounding about a 3-4, and FTs about a 1-2.
Possessions are calculated by .976 x (FGA + .44 x FTA + TOV - OREB). Do that for both teams, then average the two numbers.
All of this combines to make offensive and defensive ratings. Offensive rating is 100 x (pts / possessions). Defensive rating is 100 x (pts allowed / possessions).
