之前关於 Wade 的讨论中, RickymarU 网友 提到 eFG% = (FG+0.5*3P)/FGA 乍看下让我很纳闷如果是一个外线的加权 FG 为什麽反而把 3pointer 加权更低的 0.5 呢 原来是我笨, FG 里面就包括 3pointer 了, 所以等效的加权是 1.5 以下是我 google 到在 nba.com 中的一篇关於 nba statistics (http://www.nba.com/sonics/news/stats101.html) 有关 eFG% 的讨论: Shooting Efficiency - If there is an on-base percentage in the NBA - a statistic that has traditionally been undervalued - it would probably be some measure of a player's efficiency in scoring points. There's a stereotype that all statistical analysts think someone like Allen Iverson (who has a 41.7% career field-goal percentage) is a bad player that is untrue because Iverson's ability to create shots and get his teammates better looks is valuable. Still, being efficient with your shots is very important. The two most common ways of measuring the concept of shooting efficiency are Effective Field-Goal Percentage (eFG%) and what this site calls True Shooting Percentage (TS%). Effective Field-Goal Percentage was popularized by current L.A. Clippers Coach Mike Dunleavy and the Rick Barry's Pro Basketball Bible series. It adjusts for the added value of three-pointers by counting them as 1.5 field goals, thus make it more fair to three-point shooters than field-goal percentage. eFG% = (FGM + .5*3PM)/FGA True Shooting Percentage goes a step further by factoring in a player's performance at the free-throw line and considering their efficiency on all types of shots. TS% = Pts/(2*(FGA + (.44*FTA))) Because he is shooting 54.8% from the field and gets to the free-throw line regularly, Fortson currently leads the NBA with a 69.5% true shooting percentage. Getting the picture that he's a pretty valuable player. ※ 引述《RickymarU (失踪的力丸 )》之铭言： : 今年Wade的出手中 外线跳投占53% eFG%为38.9% : 同队的E.Jones老大哥在跳投方面的比例是77% eFG%则有48.5% : eFG%==>(FG + 0.5*3P) / FGA 将三分球加权後的综合跳投得分率 : 这项数据里大约可以当做球员在禁区外的得分能力 : 顺便找了几个当今最具破坏力的几个後卫其中几名的数据 : 跳投比率 eFG% : AI 68% 41% : Nash 79% 54.4% orz...鬼... : Ray 81% 47.6% : Kobe 71% 43.2% : Starbury 63% 47.2% 这家伙应该算後卫里除了Wade外最爱杀到篮下的 : V.Carter 70% 47.6% : T-Mac 77% 44.3% : Kidd 81% 46.6% : (去年Kidd)78% 41.6% : 乱入的长人 : Dirk 80% 45.7% : 对Wade这个一年三分球投不到50个的人来说 这几乎就可算是他中距离的命中率 : ...... --
