Approximate Value which was developed by Dean Oliver. You can read more about this formula and more at this website:
http://www.powerbasketball.com/theywin2.html Here is a quick synopsis of AV values
Credits= PTS+REB+AST+STL+BLK-FG MISSED-FT MISSED-TO
AV= Credits^(3/4)/21
The plan for the method was to end up with a scale of integers between 0 and about 20 rating players, with 10 representing an 'average' player. It was to be based upon several standards a player was to meet in order to gain points of approximate value. The whole thing was modeled on Bill James' Value Approximation method for baseball. As James did, I assigned verbal descriptions to ranges of scores in order to see if the method produced results that matched general descriptions of players. Those descriptions are as follows:
A score of about twenty indicates an exceptional MVP season.
A score of seventeen or eighteen indicates a strong MVP candidate or an ordinary MVP season.
A score of sixteen indicates an MVP candidate.
A score of fifteen indicates a definite All-Star who is a marginal MVP candidate.
A score of fourteen indicates a probable All-Star.
A score of thirteen indicates a marginal All-Star.
A score of twelve indicates a very fine season; an All-Star candidate.
A score of eleven indicates an above average regular; an excellent player playing about 1800 minutes.
A score of ten indicates an average regular or a very good sixth man.
A score of nine indicates an average regular or a good sixth man.
A score of eight indicates a fair regular or an average sixth man.
A score of six or seven indicates an average bench player or a good player playing under 1500 minutes.
A score of four or five indicates a player who plays about 1000 minutes and who doesn't deserve many more.
Scores of three or less usually indicate players who are unimpressive in limited playing time.
Shaq's AV for each year has been
1992-93 16.0 MVP Candidate (Shaq played about 3100 minutes)
1993-94 17.9 MVP season (3200 minutes)
1994-95 16.4 MVP Candidate (2900 minutes)
1995-96 11.3 an excellent player playing about 1800 minutes (1946 minutes)
1996-97 11.4 an excellent player playing about 1800 minutes (1941 minutes)
1997-98 12.8 a marginal All-Star (2175 minutes)
1998-99 10.4 average regular or a very good sixth man (1705 minutes)
1999-00 17.7 MVP season (3200 minutes)
2000-01 15.8 MVP Candidate (2900 minutes)
2001-02 13.7 a probable All-Star (2400 minutes)
2002-03 14.2 a probable All-Star (2500 minutes)
2003-04 12.4 an All-Star candidate (2464 minutes)
2004-05 13.1 a marginal All-Star (2500 minutes)
For his career Shaq has missed 16% of his games or 13+ games per year. If he played 82 games per year he would play 3100 minutes, for his career he has averaged 2580.
A second stat is Efficency rate. Efficiency is a new stat the NBA developed in 2002. It is calculated using the following formula: ((pts + reb + stls + asts + blk) - ((fga - fgm) + (fta - ftm) + to))/g
Since Efficiency is calculated on a per game basis, it is good at seeing how well a particular player has performed, regardless of the number of games that the player has played during that season.
1992-93 28.90
1993-94 33.48
1994-95 30.72
1995-96 27.33
1996-97 29.33
1997-98 28.85
1998-99 26.94
1999-00 33.82
2000-01 30.99
2001-02 28.48
2002-03 29.85
2003-04 24.93
2004-05 24.44
Another stat is Rebound rate. Rebound Rate is an excellent stat for measuring the rebounding ability of a player. It simply measures the percentage of missed shots a player rebounded while he was on the floor.
