大家好
關於Offensive Box Plus/Minus (OBPM),我想大家討論的點無非就是Curry再進攻上,
是否是比LBJ,MJ更強的球員。
但是,我想大家其實對這個數據,多少有點誤解,本人其實也不是很了解,拋磚引玉,
歡迎指教。謝謝~~
Offensive Box Plus/Minus
http://www.basketball-reference.com/about/bpm.html
1.其實這個進階數據,是BR這網站的作者所設計出來的數據,其實應該是BPM,但是其實
防守很量化,這點作者也承認,所以進攻版的BPM也就是OBPM,其實是比較有實用性的
DPM不能說沒用,但是如果雙方差距不大,其實很難斷定孰勝孰劣。
2.數據的比較,最困難的點就是"張飛打岳飛"這點很難比較,我用白話一點說,以前一場
的進攻輪轉跟現在比當然有差,這也是數據派很難克服的點,不拿不同世代比,光是
同一個球季就好,請問馬刺的節奏跟勇士的節奏一樣嗎?
在馬刺隊拿兩分的跟在勇士隊拿兩分的程度是一樣的嗎?先不管PACE的問題,光是平均單
場得分114vs103分,就知道兩隊兩隊的打法不同,所以為了"調整"通常的作法是平均每100
次的攻守,來做數據的調整。
3.承2點,這項數據有做了調整,但是用來打不同時代的球員數據,還是很粗估的,同個
時代的球員相比我想這點是勉強ok的。
4.其實說真的啦,有一個方式比一定是最準的,沒有球隊節奏,打法戰術的問題,那就是
同隊友互比,這樣講很多人會不懂,我舉個簡單例子:Kobe跟Gosal之爭,兩人同隊,
球隊節奏一樣,誰才是球隊的最有貢獻者,至少在數據方面,單比數據,這其實算客觀
了,沒有了體系的變異數,到底是一人球隊還是兩人球隊,一目瞭然。
5.另外OBPM他衡量的點是,高於聯盟平均值得多少,而不是絕對值,說到這,大家就知
道,又是不同時代不能互比的數據了。
6.好,我知道他的數據列那麼多,其實大家只想知道MJ CURYY LBJ到底誰的進攻強,
2015-2016 2009-2010 1987-1988 2002-2003
----------------------------------------------------------------------------
Stephen Curry 12.1 LeBron James 9.7 Michael Jordan 9.8 T-Mac 9.7
Klay Thompson 2.9 Mo Williams 2.5 剩下都負數 Garrity 1
Draymond Green 2.0 Daniel Gibson 0.8
補上該隊USAGE%
2015-2016 2009-2010 1987-1988 2002-2003
----------------------------------------------------------------------------
Stephen Curry 32.5 LeBron James 33.5 Michael Jordan 34.1 T-Mac 35.2
Klay Thompson 26.4 Mo Williams 22 Garrity 15
Draymond Green 18.8 Daniel Gibson 14.2
補上該年度的OBPM前三名
2015-16 NBA S. Curry (12.10) R. Westbrook (7.53) C. Paul (7.40)
2009-10 NBA L. James (9.74) D. Wade (7.37) M. Ginobili (5.59)
2002-03 NBA T. McGrady (9.79) K. Bryant (6.08) R. Allen (5.56)
1987-88 NBA M. Jordan* (9.82) C. Barkley* (8.29) L. Bird* (7.46)
*
2015-2016 K. Durant (6.94)
2002-2003 S. O'Neal(5.52)
<分析>
任何的進階數居,其實都是要搭配其他數據輔助,才能產生出效果,USAGE就是一個很
百搭的配件,USAGE簡單說就是被使用率,這個之前我在馬刺版有解釋過,別再翻成自幹
率了。
回歸正題。看完上列數據。
<勇士>人才都有好的發揮,良好的效率加上大量的被使用,戰績要差也難,KT進攻強出手
數也不少,人盡其用。Curry效率這麼高但使用率僅僅只有32.5,但KT卻有著26
的使用率,浪花兄弟還是存在的,而不是Curry孤單一人。
<騎士>那年帶刀護衛MO很稱職,進攻強也手出手權,騎士的第二把刀,DG偶有佳作,但其
效率有限,OBPM其實沒很好看,但已經是全隊第三了,可見騎士進攻有多依賴這三
人
<公牛> 辛苦了,MJ,和他的快樂夥伴,全隊的進攻效率都低於聯盟平均,只能靠神來救
了,34.1%的使用率,真的很血汗,老實說,以球隊角度看,公牛已經到底了,
在怎麼打還是這樣。不然你要把MJ操到36%的使用率?
<魔術>辛苦了,麥迪,和他的不快樂夥伴,全隊的進攻只有一人高於聯盟平均,進攻全看
小麥,35.2%的使用率,比神還累,再次強調,麥迪的OBPM不能直接和MJ比,畢竟
時代球隊均不同,惟一相同的就是隊友都很廢,團隊能力已經無淺力了。
上述四隊有三隊都很依賴隊上的神主牌,惟有勇士例外,Curry能有這麼優秀的OBPM,教
練的使用其實很關鍵,加上隊友明顯比其他人強不只一個檔次,戰績好可以預期的。
最後我還是要說,你想只用一個數據而且還是張飛打岳飛式的比較,這是不可能的,可以
洗洗睡了,數據是要互相輔助的,主要的目的的還原當時的情形,勇士的強在這上面的
敘述一覽無遺,騎士帶刀護衛之名,也非浪得,喬丹麥迪當年的一夫當關,也是因為隊友
太廢,其實這數據的很好的指標,希望大家能用正確的方式使用。
