In the boxscore, we have steals and blocks, which don’t really tell us much. Two of the league’s top five in total steals plus blocks – Josh Smith and Andre Drummond – are Pistons. The Pistons are awful defensively and worse when Smith and Drummond are on the floor together than they are when one or both is off the floor. NBA.com/stats tells us how many points per 100 possessions a player’s team has allowed when he was on the floor, a category dominated by players on the league’s best defensive teams. 防守是很难量化的。攻守数据中虽然有抄截和阻攻，但是实际上它们不能反映全部，在联 盟中抄截和阻攻总和的前五名，其中有两位是活塞的球员，Josh Smith以及Andre Drummond。不过活塞的防守糟糕透了，而且当他们同时上场时，状况还会更差劲。 NBA.com/stats提供了所有球员在场上时每100次球权的球队失分，这个项目的前几名理所 当然地被联盟中那些身处防守强队的球员所占据。 To be considered for the Kia NBA Defensive Player of the Year award, you should be on a good defensive team. The last player to win the award that wasn ’t on a team that ranked in the top 10 in defensive efficiency was Dikembe Mutombo in 1997-98. And 12 of the 15 winners since then (including each of the last six) played for teams that ranked in the top five. And you can find plenty of great defensive players in this season’s top five teams in defensive efficiency. Indiana (1) has both Paul George and Roy Hibbert. Chicago (2) has Joakim Noah and Taj Gibson. Golden State (3) has Andre Iguodala and Andrew Bogut. Oklahoma City (5) has Serge Ibaka. 想要成为年度防守球员的候选人，你势必要在一支防守优秀的球队才行。上一位球队防守 效率不到前十名却拿下这个奖项的人是1997-98年的Dikembe Mutombo，而且过去15年来有 12位年度最佳防守球员的球队防守排名联盟前5名。你可以从本季防守效率前5名的球队找 到很多防守出色的球员，包括溜马(第1)的Paul George和Roy Hibbert，公牛(第2)的 Joakim Noah和Tai Gibson，勇士(第3)的Andre Iguodala和Andrew Bogut，雷霆(第5)的 Serge Ibaka。 It’s hard to pick a Spur for DPOY candidacy when none of them have averaged 30 minutes per game. Beyond the top five defensive teams, Chris Bosh, Marc Gasol, Dwight Howard and DeAndre Jordan could be candidates. Their teams all rank in the top 12 in defensive efficiency, and Howard’s Rockets have only dropped out of the top 10 since he started missing games. This season, we have SportVU data to tell us how well opponents shoot near the basket when a player is there defending it. And we can supplement that with data on how often opponents actually shoot near the basket when that player is on the floor. Big guys should get credit for keeping the other team away from the basket, after all. 要从马刺选一个DPOY的候选人有点困难，尤其是他们没有任何一个人平均上场时间超过30 分钟。除了防守前5名的球队外，Chris Bosh、Marc Gasol、Dwight Howard和DeAndre Jordan也可能是候选人，这些人的球队至少都在防守效率排名前12，其中火箭正是从 Howard缺阵之後才跌出前10名的。本季我们可以透过SportVU的资料去判读一名球员在篮 下时对手的进攻表现，而且还要搭配当他防守时对手攻击篮框的次数来比对才行，毕竟趋 使对方远离篮框出手也应该被考虑做为防守绩效的计算才是。 There’s more to defense than protecting the rim, though. For a big man to be an impact defender, he has to be able to contain ball-handlers on pick-and-rolls. This is where a guy like Bosh can show his value on a team that defends like the Heat. It’s also where a guy like Drummond still has a lot of work to do. SportVU has numbers on how efficiently opponents have scored when a player is the help defender on pick-and-roll. 然而防守不是只有保护篮下而已，对大个子来说要成为有影响力的防守者，他还必须在挡 拆时有效吓阻持球者的攻势，这正是Bosh在热火的价值，而这也是Drummond还需要努力加 强的部份。SportVU提供了这个部份的资料，以下的表格列出他们在协防挡拆时对手得分 的效率。(表格请见上列网址) There’s a lot that goes into these numbers. They’re from all possessions in which that player defended a ball-screen and the results (a score or no score) could be several passes away. So they do depend on his teammates quite a bit. Still, we can see that Bogut, Hibbert and Noah have distinguished themselves as both rim protectors and pick-and-roll defenders. The other thing we can look at his how much of an impact these guys make on their team defensive numbers. 这些数据其实把很多状况都包含在内，所有对手有执行挡拆的回合都会被计算进来，即使 出手(无论有没有得分)可能在好几次传球之後也一样，所以这也和队友的防守有点关系， 不过我们还是可以发现Bogut、Hibbert和Noah同时在保护篮框和防守挡拆上都很杰出。另 外我们还可以研究这些家伙在场上时对球队防守数据的贡献。 If a team has better defensive numbers when a player is off the floor, it doesn’t mean that he’s a bad defender. The Thunder are typically defending the opponents’ best players when Ibaka is on the floor and their subs when he ’s off. Who these guys are being replaced with also plays a role. Hibbert’s the best rim protector in the league, but Ian Mahinmi is also a very good defender. But the on-off court numbers make a strong case for Iguodala. The Warriors have been a much better defensive team with Iguodala on the floor and Bogut off than vice versa. Opponent shooting numbers, when you compare Iguodala to some of the league’s other good defenders at the small forward position, also make a case. 如果球队在他休息时防守效率比较好，并不意味着这名球员的防守不好，像雷霆的Ibaka 在场上时通常守的是对方最好的阵容，相对地他休息时队友守的是替补。还有当球员休息 时替代他上场的球员也很关键，像Hibbert是联盟中最好的禁区守护神，但是Ian Mahinmi 也很不错，因而影响到Hibbert的数据。不过on-off的数据对Iguodala非常有利，勇士在 场上有他却没有Bogut时，防守的表现比反过来还要好，当你拿Iguodala和联盟其他小前 锋中的顶级大锁来做比较，数据还是对他有利。 Ron Artest (2003-04) and Gary Payton (1995-96) are the only perimeter players to win Defensive Player of the Year in the last 25 years. And it’s hard to argue against a pick of either Hibbert or Noah as the anchors of the two best defensive teams in the league. But Iguodala should definitely be in the conversation. He’s the biggest reason why the Warriors have jumped from 13th in defensive efficiency last season to third this year, and why the Denver Nuggets have gone in the opposite direction (from 11th to 21st). Ron Artest(2003-04)和Gary Payton(1995-96)是过去25年来唯二赢下年度防守球员的外 线球员，你也很难去质疑选择Hibbert或Noah的人，因为他们是联盟中两支最佳防守球队 的支柱。不过Iguodala还是值得被讨论，他是勇士能将防守效率从上季第13名提升到本季 第3名的最大因素，同时也是丹佛金块退步的原因(从第11名掉到第21名)。 --
