基於+/-, 小貝是比林更有用的團隊成員嗎？

小貝從上季到這季總是 +/-值比林高。林的值經常倒數第一。

(NBA +/-定義
Plus/minus began as a hockey metric, and has been kept as an official NHL statistic since 1968. Around 2003, Roland Beech of 82games.com brought this concept to NBA basketball...and a few years after that, the league made +/- a part of it's official boxscore statistics.

Interestingly, this metric is much more meaningful in basketball than it is in hockey, even though it took much longer for the NBA to begin using it. The more scoring there is in a game, the more useful this statistic becomes. Plus/minus is a useful way to determine a player's value to his team, because it encompasses everything a player does on the basketball floor, even things the NBA doesn't keep official statistics on.

An example of Plus/minus is as follows: let's say a player's team was 7.5 points better than their opponents when he was in the game (+7.5). When our player was not in the game, however, the team was 3.3 points worse than their opponents (-3.3). To find this player's +/- rating, you simply take the difference of the two numbers, which yields a rating of +10.8.)

所有跟帖： 

• 小林是擦pg的，和替補為主力休息頂缸的。球隊得分的時候不需要在場，自然+-低。 -萬綠叢中- ♀ (0 bytes) () 12/14/2013 postreply 08:05:49

• 這個數據意義不大，取決於對方上場的是主力還是板凳。 -正球迷- ♂ (0 bytes) () 12/14/2013 postreply 08:06:17

• 去年對首發，今年對板凳，是不是對手一看小林板凳，也都改變首發了。 -jiangwen999- ♂ (0 bytes) () 12/14/2013 postreply 08:12:14

• 這+－處決於兩個原因。1．教練沒有派林最適合最有效率的5個隊員同時在場 2．其它。 -talkatwxc- ♂ (0 bytes) () 12/14/2013 postreply 08:37:59
