About Efficiency - NBA

剛剛在NBA 板上面看到有人問合約的價值性，然後上網站查了一查，看到有
Efficiency 這種可以拿來作為評估一個球員價值的指標..覺得蠻有趣的

Efficiency Formula:
((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G

從上面的式子看來，這個efficiency並不能看出這個球員的專長( 攻擊乎？防守乎
？) ，是一個從綜合數據去判斷這個球員的價值的指標，這方面我的想法是：是不是可
以粗略的從Efficiency直接看出這個球員價值多少錢？( 當然是粗略的，也就是在等級
上面來說；搞不好只能分成：很貴、普通貴、不貴、很不貴之類的吧(笑) )

不意外的，在前50名之中，都是一些很出名( 最少我都有聽過啦:p )的球星。不過
我現在想說把這個排名跟聯盟薪資排名做做比較；另外還想看看團隊的總Efficiency跟
團隊戰績有沒有正相關；看還能不能試著從Efficiency表現裡面簡單的找出薪資被低估
的球員... 抱歉，因為要睡覺了，所以啦哩啦雜先把想法記下來一下

下面則是聯盟2003-2004 efficiency Leader 的數據
