Player Ratings

This is a short overview over how Player-Ratings for nbaliveleague.com are determined. They can be divided into two groups.

1. Derived Ratings : These are ratings that are directly derived from the statistics players put up in the NBA.
   
   
   • FGBASE: 2-point FGs per game, 2-point FGs per minute, 2-point FG%
   • THREEPTBAS: 3Ps per game, 3Ps per minute, 3-point FG%
   • FTPBASE: FTs per game, FTs per minute, FT%
   • DNKABILITY: Dunks per game, Dunks per minute, Dunks per FGA
   • STLABILITY: Steals per game, Steals per minute
   • BLKABILITY: Blocks per game, Blocks per minute
   • OREABILITY: ORebs per game, ORebs per minute
   • DREABILITY: DRebs per game, DRebs per minute
   • BALABILITY: Assists per game, Assists per minute
   • FATIGUE: Minutes per game
   • PRIMACY: FGA+FTA per game, FGA+FTA per minute
     
   
   Calculation: Above ratings are based on the last and current NBA season. At the start of the NLL season (December) there is not enough data available to use the current season only. So the last season is taken into account also. With each update the data from last year will be given less and less weight until it is taken out completly.
   
   Initial patch: Last NBA Season + Current NBA Season
   Week 5 update: Last NBA Season*0.75 + Current NBA Season
   Week 10 update: Last NBA Season*0.50 + Current NBA Season
   Week 15 update: Last NBA Season*0.25 + Current NBA Season
   Week 20 update: Current NBA Season only
   
   Players need to have at least 15 games to qualify for derived ratings. Otherwise all of their ratings are taken from the outside source. This mostly happens for rookies, free-agents and long-term injured players.
   
   All players are first ranked per position in each of the above categories. The ranks are then summed up for each of the ratings and those total ranks are transformed into ratings.
   
   The transformation is again done by position. The ranges used for each rating are basically taken from EA's original patch, but extreme outliers are removed.
   
   The exact parameters for the transformation are determined at the beginning of the season, so that mean, median and variance correlate as much as possible with the original ratings. Those parameter will stay the same for the rest of the season.
   
   
2. Qualitative Ratings : These ratings are taken from an independent outside source. At this point it is NLSC.
   
   
   • OFFABILITY
   • DEFABILITY
   • SPEED
   • QUICK
   • JUMP
   • DRIBBLE
   • DSTRENGTH
   • DHARDY: Not in use. Set to 50 for all players.
   • DSHOOTRANG
   • INSIDESC
   • CLUTCH

Note : In case gameplay cannot properly be adjusted with Slider-Settings, the ranges for ratings are changed to suitable values.

Ratings for player not (yet) included in the outside source will be determined by the league.
